Hi Adam,

Did you succeed to get USB OTG over PMIC to work on this 3.14+ version?
I want to use it as USB device only and I can't load any gadget (I need mass storage gadget).
There is a error:
#modprobe g_mass_storage file=/dev/mmcblk0p1
modprobe: can't load module g_mass_storage (kernel/drivers/usb/gadget/legacy/g_mass_storage.ko): No such device
or
# modprobe g_serial
modprobe: can't load module g_serial (kernel/drivers/usb/gadget/legacy/g_serial.ko): No such device

Although I compiled kernel with Mass Storage Gadget and Serail Gadget modules and I can see it in /lib/modules/4.2.6/modules.dep file.

When I try to load
modprobe phy-twl4030-usb

Output is:

PS. Just to confirm that adding tcxo-clock-frequency = <26000000>; in devicetree solve my problems with WiFi. I see that you already upload it at Kernel 4.5.
Also WiFi performance together with new UART driver (8250-omap) is much better than on BSP 2.4.4. Same application which is some kind of bridge between UART and WiFi have higher throughput on Kernel 4.2 than on BSP2.4-4.

Hi Adam,

USB works. No need for changes at device tree file.
First load
modprobe phy-twl4030-usb
then
modprobe g_mass_storage file=/dev/mmcblk0p1

Dragan

I was testing yesterday, the other gadget functions and I found that am having difficulty getting them to work, but I haven't tried the USB. I have been using http://processors.wiki.ti...x.php/Usbgeneralpage as a source for help in making sure it's all configured.


I am glad to see you're getting better performance. The 8250 driver should also reduce power consumption a bit by being DMA controlled. I haven't tested it very much, but I was able to get it working. I am trying to get the tcxo-clock-frequency = <26000000> patch pushed into the the 4.4 and older kernels as well, but the maintainer is busy with some 4.5 bugs, so he hasn't been available very much.

FYI, myself and another person independant of Logic PD made a bunch of U-boot patches to bring it up to date. If you haven't checked out the latest main branch of U-boot, you may want to consider it. At a minimum, I would suggest reviewing the patching on U-boot and grabbing the omap3_logic appropriate stuff. It will eliminate X-Loader and U-boot will build MLO instead.

The latest patches will enable ECC BCH8 and add UBI support.

adam

Great! I will check it.

Regardless, I still think that LogicPD should consider making new official BSPs which are based on Kernel 3.14+ versions with devicetree.

Regards,
Dragan

We're working internally to discuss options. Part of the problem is that the baseboard uses an ISP1763A USB controller and the mainstream Linux doesn't have that driver available.

Linux 4.6 may have a few more items enabled in the device tree if the mainstream OMAP maintainer has time to review them.

adam

Hi Adam,

Is it for setting appropriate FCC levels for WiFi only needed to use NVS file from LogicPD BSP2.4-4?

I copied it to my Linux 4.2 system and run
calibrator set nvs_mac /lib/firmware/ti-connectivity/wl127x-nvs.bin 00:00:00:00:00:00
to set default MAC address from TI chip, since can't read it from ID eeprom.

Regards,
Dragan

The only FCC approved power levels from from the NVS file from the stock BSP. It is only certified for use in US and Canada. In our BSP the other countires have been removed from the CRDA database. Since the mainstream Linux opens that up, you'll need to make sure to restrict it to US and Canada and disable the DFS bands if you want to remain compliant.

adam

For those of you who have been following the device tree progression,I have some updates.

Kernel 4.5:
* Should have basic support for the Type 15 Display from Logic PD as well as
* TSC2004 Touchscreen support added.

If you would prefer the 4.4 series kernel, the logicpd device tree files appear too work without issue on the 4.4 kernel. Some small patching is necessary on the panel-dpi driver, but most customers use a custom LCD. For those interested in the patch, let me know and I can help.

Kernel 4.6:
* Add basic support for the Parallel Camera port using the Leopard Imaging sensor referenced in the Linux BSP. It's highly untested, so there might be more work to do. (older compatibility is unknown)
* Add the I2C EEPROM on the SOM (Should be backwards compatible with 4.2+ kernels)
* Add SPI EEPROM on the baseboard. (Should be backwards compatible with 4.2+ kernels)

Pending a review, 4.6:
* PWM controlled back light support (This won't work until 4.6 due to driver missing in kernels until 4.6)
* Support for Type 28 display. These patches should get pushed soon. (Should be backwards compatible with 4.2+ kernels)

U-Boot (upcoming in 2016.03):

* SPL support has been integrated which removes the need for X-Loader (Thanks to Derald Woods).
* Enable BCH8 ECC which uses some hardware and some software support, but it makes the driver more inline with mainstream OMAP3 processors.
* UBIFS Support in NAND.
* Android Fastboot over USB

To-Do: The partition table is not device tree friendly, so the kernel will need the device tree appended to the kernel, and the partition table is probably not large enough to support that, so people desiring that will have to manually modify the partition table. Once I can get some people to review a proposed partition table change, I will push the patches to the mainstream u-boot and kernel communities for review.

Not Working: The ISP1673A USB controller does not have mainstream Linux support as of right now. Users who need this in their application should continue to use the release BSP from Logic PD and avoid using the mainstream Linux.

For anyone following the device tree updates, Kernel 4.4.3 was released a few days ago. This fixes the WiFi bug due to a missing entry.

For people needing Video, you can use the 4.5-RC device tree files in the more stable 4.4.3 kernel.

https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/arch/arm/boot/dts/logicpd-torpedo-37xx-devkit.dts?id=refs/tags/v4.5-rc5

and

https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/arch/arm/boot/dts/logicpd-torpedo-som.dtsi?id=refs/tags/v4.5-rc5

Both appear to be backwards compatible with the 4.4.3 kernel, but you'll need both in order to make the extra features operate properly.

adam

Dear commiters,

May be I'm writting in wrong discussion, but could you advice me where could I get a compiled 4.5 kernel, appropriate RFS and boot-loader for DM3730 Torpedo + Wireless SOM? May be there is yocto project modules for the SOM?

I am working on an alpha-build that will compile the kernel and make a RootFS, but it's not coming together quickly.

I can give you some suggestions, however.

I have been using Buildroot to create the RootFS. It's a menu-driven interface that allows you to select different tools, libraries, and other software.

https://buildroot.org/

You can download the 4.5 kernel, and point Buildroot to that kernel and it will build the kernel and the filesystem together as a package.

I believe you can also download U-boot and ask Buildroot to build U-boot, the Kernel and the RootFS all as one big group.

Unfortunately, we have not spent much time working with the Yocto project or any Open Embedded based system, so I cannot say how to configure it.

I have a couple of customer contracts that I must complete first, but once those are complete, I should be able to get back to creating and documenting a virtual machine for building the 4.5 or newer kernel.

adam

Adam,

Thank you for your advices and for your great work. I'll try to build using buildroot.
Do you creating the virtual machine for your own projects or for your customers?

SY, Anton.

The plan is to have it working in an alpha-state that should do basic functionality. My goal is to get it posted on the web site within the next few months. Linux 4.6 should have support the PWM controlled backlight which will make dimming the screen possible.

It won't go through the Logic PD software quality testing procedures, and it won't be officially supported. However, it should form the basis for people who want to use a modern kernel. If people want a services contract for services work, we can include a certain amount of testing of that software in the customer's application.

adam

I would highly suggest the 20016.03 version of U-Boot as it's more feature complete.

ftp://ftp.denx.de/pub/u-boot/u-boot-2016.03.tar.bz2

If/when you do a build, I have found that using multi_v7_defconfig and omap2plus_defconfig are the best default configs for the T+W

multi_v7 doesn't have all the drivers enabled, but omap2plus has some strange behaviour on poweroff.

For U-boot, omap3_logic_defconfig is the the default configuration to use.

If you need the the Logic PD display to function, I have an extra patch for the panel driver(s) that I can give you. If you don't have video or don't use the Logic PD panels, the patch is irrelevant.

adam

Hi Adam

I have used the defconfigs as you defined and tried to boot Linux-4.5.0-rc5 with 2016.03 u-boot from x-loader 1.42 as I couldn't get u-boot to boot from the MLO directly.

Although now I just get a hang at Starting kernel...

I tried to enable arm debugging in u-boot at physical base address 0x4806a000 as I understood OMAP34XX_UART1 = OMAP34XX_L4_IO_BASE + 0x6a000 where OMAP34XX_L4_IO_BASE = 0x48000000

Although I still receive no error messages.

Have you managed to make any progress on the alpha-build ?

Cheers

H

Can you post a log of what you see?

U-Boot 2016.03 should product MLO, so you shouldn't need X-Loader anymore, but the DM37 is very specific that MLO needs to be the first file loaded onto the card. You may have to do a fresh format the copy MLO first.

I am not sure which compiler you're using, but I recomend using Buildroot to build both the toolchain, rootfs and kernel.

Can you post a log of what you're seeing?

With omap2plus_defconfig, U-Boot 2016.03 and the Buildroot, I can get the following:

Welcome to Buildroot

Hi Adam

 

Thanks alot for the quick reply you were absolutly right about buildroot already making the MLO although I didn't realise it wasn't going to be in output/images and in stead in the custom u-boot locale.

A couple of questions:

I had to manually cross compile the  logicpd-torpedo-37xx-devkit.dtb as buildroot didn't make one is this normal ?

I did this by following dtb section of this page http://www.armadeus.com/w...nel-with-device-tree

Secondly which kernel headers are you using ? I am going for 4.5-rc5 with 4.4.3 headers as it would take some manual editing of configs to take buildroot to newer headers is that acceptable.?

Here is my boot log:

I greatly appreciate your advice. 

 

Thanks

Also which filesystem are you using Ideally I'd like to use ubifs.

But for now I have this setup to match the boot args as I would like a successful boot.

 

I have noticed my kernel and DT are larger than yours as I may have extra /  different packages and drivers although this shouldn't be the problem as I should add I have already tried these boot args as well

console=ttyO0,115200n8 ignore_loglevel early_printk no_console_suspend root=/dev/mmcblk0p2 rw rootfstype=ext4 rootwait display=15 ignore_loglevel early_printk no_console_suspend mtdparts=omap2-nand.0:512k(MLO),1920k(u-boot),128k(u-boot-env),6m(kernel),-(fs)
