WiFi Performance Configs and BSP 2.4-4 1811 8
Started by Joshua Pagnotta
I was wondering if the defconfig.wifi-performance delivered with BSP 2.4-4 was updated and working. I'm assuming not because if I diff it against the standard defconfig in BSP2.4-4 defconfig.wifi-performance still references old u-boots and Linux kernel images whereas defconfig references 2.4-4 files. Also, what in defconfig.wifi-performance is actually changing the configuration to improve performance. The only significant deltas I see are CONFIG_PKG_KERNEL_PRECONFIG='omap3logic_defco...

How to Activate SPI Signals in the BSP 1650 11
Started by Derek Valleroy
Hello,
I'm trying to figure out how to activate the SPI pins that I have registered in the kernel. In particular, I need my chip-select pins to go high as soon as they are registered, but it appears they stay low until I open up the SPI device in user space. I am registering the SPI pins in the kernel with a spi_register_board_info() call in the board-omap3logic.c file. I'm using spidev for the SPI.
Any suggestions
More Info:
I have a user space application that opens the SPI device and com...

CAM_D6,GPIO_105 pin access 1416 2
Started by William Deninger
Using Torpedo SOM DM3730-30-2780AKCR-A with SDK board.
I have had success setting output level (direction=out, value=0,1) for cam_d3,cam_d4 and cam_d5.
But no success changing cam_6 and cam_d7. They seem to remain at 0 (GND). Similarly, when injecting a signal onto the line and setting the GPIO direction to 'in', it fails to read back anything other than '0'.
I have removed jumpers on JP5 thereby disabling the camera buffer from driving the line, and am monitoring the signal on t...

LogicPD Linux BSP 2.4-4 patch sequence for Linux 3.0.101 2672 12
Started by Derald Woods
Now that Linux Backports appear to be a part of the kernel equation, what is the proper patch sequence for Linux version 3.0.101
linux-3.0.101 -> backports-.patch -> kernel-3.0.101-01-dm37x-r38324.patch
Having the correct sequence will help build a proper BSP 2.4-4 git branch for Linux.

SD card power 1272 1
Started by Bret Pollack
What would cause the SOM to turn off the 3.3V supply for SD card while we are trying to boot from the SD card Once the power is down I get a long series of SD card read errors, which I expect if there is no power. This only happens with some of our devices. Noise Something else
Thanks

Procuring ISP1763A 1337 1
Started by Joshua Pagnotta
We are interested in upgrading our design to include the two additional host USB ports on the development kit which require the integration of the ISP1763A. We have been unable to find a supplier for this chip without very long lead times (15 weeks) and large minimum buys (1000). Do you have know of any vendors or know of a way to procure this chip more readily

migrating from DM3730 20-1880AGIR-A to 20-2880AGXR-A 1200 4
Started by mvly
I am in the process of migrating from the 1880AGIR-A to the 2880AGXR-A. From the product brief pdf, the only difference is the Clock Speed.
However in my Hardware design, only the 1880AGIR boots. The 2880AGXR-A does not. It self-reboots over and over when running android.
Is there something I need to change in the u-boot or kernel to make it boot fine

How to use J19 (USB OTG) for USB communication? 2569 7
Started by Derek Valleroy
Hello,
Does anyone have advice for using J19 (USB OTG) for communicating with a USB device, like a HID
There are forum posts about using this for battery charging, but I need to get actual data transfers working. Other USB ports on the kit go through a USB controller chip, which has driver support in LTIB. However, I couldn't find a configuration in LTIB that supports the J19 (USB OTG) port. J19 appears to go to the PMIC USB transceiver on the SOM. There is an option for enabling the U...

Is it possible to integrate a newer version of libusb by simply replacing the current package with a newer one per the 'Integrate New Package' section of the User Guide or is there more to it than that I'm looking for hotplug support which does not exist in version 1.0.9 in the 2.4.4 BSP.

Detecting Power Loss 1199 1
Started by Alex Johnson
Hey, I am currently working on implementing a kernel module that will be able to react to a sudden power-loss on the system, and quickly perform necessary 'housekeeping' functions in order to cleanly shut down the OS before the few seconds of backup power is depleted. Is there a simple way to detect a loss of power to the Torpedo that I can utilize I'm going through the documentation, but so far I've been coming up empty. Thanks!

Repercussions to Running LTIB as Root 1390 3

I know a solution would be to add another user with non root privileges and run it as that but would like to stray away from that approach and figure out if I can just...

MAC address of the LAN9221 chip on the baseboard 1250 1
Started by Derek Valleroy
Hello,
How can I set the MAC address of the LAN9221 chip on the torpedo baseboard The datasheet of the LAN9221 chip says that it can be configured to use a built-in address, or load one from the EEPROM on power-up.
Is there a command-line utility, or maybe an LTIB setting to configure the LAN9221 chip
Regards,
Derek Valleroy
