Hi again,

i've got question, i want to apply patch to kernel for torpedo and I've followed instructions:
https://buildroot.org/downloads/manual/manual.html#_providing_patches
but it didn't work. How can I apply patch?

There are two ways if you're using Buildroot:

1. Manually apply the patch
Going into output/build/linux-4.4.y
Applying the patch. (patch -p1 -i (patch to patch)
go back to buildroot home directory
make linux-rebuild

2. If you want Buildroot to autoapply the patch:
place the patch in the Buildtroot home directory
make menuconfig
select Kernel
select 'Custom kernel patches' and type the name of the patch

Then either do all of step 1 to avoid rebuilding the whole kernel or
make linux-dirclean (to remove the existing build)
make linux (to rebuild and patch)
make (to re-install all the new kernel modules to the output image)

Hi,

I've got another question: how do i have to configure my u-boot to pass to the linux suitable parameters about video (display, resolution. bootargs) ?

Thanks for reply about patching, it worked.

The modern Kernel uses a device tree to configure the display parameters. You'll want to look at arch/arm/boot/dts/logicpd-torpedo-37xx-devkit.dts

In there are all the display parameters. For for a container called panel-timing.

It will have the clock frequency, resolution, and a variety of other settings. When you compile the device tree, U-Boot will pass this updated tree to the kernel and the drivers will take these settings and act accordingly.

Details of the device tree can be found: Documentation/devicetree/bindings/display/panel/panel-dpi.txt and Documentation/devicetree/bindings/display/panel/display-timing.txt

I can't remember if I sent you the 4.4.y patch to enable video and touch screen, but there are a bunch of video components that were added in kernels after the 4.4 which either need to be ported back.

Hi Adam,

I'm trying kernel 4.9 for my torpedo, can you send me patch to that kernel to enable backlight etc?

Thanks

The timing of the Logic PD Type 28 Display requires that the LCD be enabled before the backlight, so I configured the defconfig to pull the LCD panel driver and display sub-system into the kernel and the backlight is pulled in as a module.

If the modules are not being automatically loaded, make sure you load pwm_omap_dmtimer and pwm_bl.

pwm_bl is the backlight interface, and pwm_omap_dmtimer is the timer drives it.

Hi Adam, thanks for patch and config.

Can you send me appropriate device tree for torpedo for kernel 4.4.y? (not 4.9). I have many problems with confoguring usb ports (kernel doesn;t see anything if I plug in USB drive or 2nd mmc card in J29), i can't configure properly u-boot (no display in linux) and I don't have ethernet support...

Regards
Przemysław

I've got another request for you - can you explain me (step by step) what should i do to run ubuntu (fe. 14.04 LTS) base on torpedo?

The Mainline Linux Kernel is beta, and not all features are fully functional. If you'd like assistance getting some of these features functional again, we do offer design services where our software engineers can contract with you to troubleshoot and/or design in the missing code. Let me know if you want one of our account managers to contact you.

The only USB port that is functional is the OTG Port. There is no mainline support for the ISP1763, so the USB Host ports are non-functional. The USB OTG port should function, but you'll need to make sure you have modprobed a USB Gadget even if you want the OTG port to work as a host. For simple host functions, I usually modprobe g_zero.

The second MMC slot was never enabled in the device tree, so by default it doesn't work.

Ethernet should be working on 4.9, I am not sure why you would be having problems. Are you using our base development kit? It wasn't clear to me from the previous message what the Ethernet issues are. Are you having Ethernet issues in U-Boot or Linux?

Having said this, I can send you patches for the 4.4 kernel, but the same conditions I stated above are true for the 4.4 Kernel. It will take me a few minutes, but I'll send you a private e-mail with those patches.

Unfortunately, I don't have instructions for running Ubuntu on the Torpedo. Our baseline RootFS is based on Buildroot. If you'd like to utilize our design services, I can have an account manager contact you. Depending on volume and annual usage, everything is negotiable, and we have people who can assist.

Thanks Adam, I'll try with kernel 4.4.48 (kernel 4.9.y hasn't compiled succesfully :( )

Hi Adam,

i've got questions: when will be avaliable full version of mainstream linux for torpedo (not beta) ? Full version - with configured LCD, usb, ethernet etc. You have plans to make your own linux distribution for torpedo?

Przemyslaw

We don't have any set dates, but I am pushing to have the 4.9.y kernel become the basis for the next released BSP to avoid the backporting for 4.4.y. The original 4.4 Beta was done by me alone at home in my spare time. We had one customer adopt it and we tested a significant number of non-wireless Torpedo features including video and touchscreen.

I'll talk with an account manager and some others to see what we can do.

We just released an updated beta BSP on our support site based on the 4.4.76 kernel.

The release note are here: http://support.logicpd.co...talid=0&EntryId=3128

The updated VM is here: http://support.logicpd.co...talid=0&EntryId=3144

and the updated user guide is here: http://support.logicpd.co...talid=0&EntryId=3053

You'll need to be logged in to make the links active.

We're still planning a 4.9 kernel, but it's not finished going though our quality and review testing. There is a high degree of probability that the 4.14 kernel will be support at some later time, but it's not finalized yet.

A beta BSP based on Kernel 4.9 is in the final stages of our quality testing and reviews.

It adds instructions for using the Audio and Camera capture (albeit slower than using the DSP from our 3.0 kernel due to TI's dropping support for the DSP)

It still will not have DSP, ISP1763 or 3D acceleration support due to lack of community support and/or vendor support for those devices.
