- BD 08:02 PM MitySOM-335x (ARM Cortex-A8 Based Products) Software Development: RE: Is ADC supported in the 3.2 Linux build?
- Alex,
The main documentation for this is provided by TI: http://processors.wiki.ti.com/index.php/AM335x_ADC_Driver%27s_Guide
First check to see if @/sys/devices/platform/omap/ain/ain[0-7]@ exist on your booted system. If they do, p... - I need a single ADC input for an ambient light sensor, and would like to use one of the pins not needed by the MitySom 335x dev kit touch screen, ain7.
What do I need to do under the current Linux to get a single reading from this p...

- Alex/Jon/Tom,
Further to this problem, we have now had a few units where this problem can be seen. We have used the CRC check to verify that the data being read from NAND is indeed corrupted.
Interestingly, the two units where we ...

- Benedikt,
I am not aware of any known usb bugs with the l138 u-boot. It is also not a feature that we use often. Have you been able to reproduce this on our devkit to try and rule out a potential hardware problem?
Its also possib...

- Hej hej,
I encountered a bug which is related to different usb sticks within u-boot. The USB-OTG port at our custom board is only used as a USB Host.
Some USB-Sticks are only discovered by u-boot using "usb start" if I run usb star...

- Alright glad its working.
- IS 11:29 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: Serial flash of u-boot-ubl.bin not working
- Thanks. That clears that up. Now to load code sourcery and see if I can compiler makefiles. Trying to use CCS 6.0 but all the code seems set up for cygwin gcc or CCS 3.3 (not available). I may ask more questions later.. ;-)

As I understand it, the UBL requires a special header to load the u-boot.bin file. The serial loader program auto add... - IS 11:10 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: Serial flash of u-boot-ubl.bin not working
- Ok. The u-boot.bin from the images of the MDK is installed and has bootelf in the help.
So the u-boot-ubl is only for the ftp download? Is that the convention? Is that my error? - JC 11:07 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: Serial flash of u-boot-ubl.bin not working

Okay thanks. The MDK u-boot should work with Starterware. - JC 11:04 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: Serial flash of u-boot-ubl.bin not working
- Just checked and it appears that our current MDK u-boot has the bootelf command. [[Board_Support_Package]]
MDK_2014-01-03/images/u-boot.bin should be what you need.
The following guide has instructions for updating using tftp but i... - IS 11:00 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: Serial flash of u-boot-ubl.bin not working

- Where did you get the u-boot-ubl.bin with bootelf?
- IS 10:51 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: Serial flash of u-boot-ubl.bin not working
- Note: I downloaded the images assuming they were ok for serial. I am not up to compiling with cygwin yet. I have bash but not the tool chains (I think).
- IS 10:48 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: Serial flash of u-boot-ubl.bin not working
- Oh, and I have used kermit to download. Not sure of all the parameters to load uboot properly. I have a background with embedded systems but no ARM/Linux. Struggling a bit.
- IS 10:46 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: Serial flash of u-boot-ubl.bin not working
- I have the u-boot.bin (older version without bootelf) and the u-boot-ubl.bin file (new version with bootelf). The documentation shows the load of uboot from uboot using ethernet. Using the serial loader, it seems to load ok, but then doe...
- JC 10:04 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: Serial flash of u-boot-ubl.bin not working

- JC 10:02 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: Serial flash of u-boot-ubl.bin not working
- Also note that if you are in u-boot, you can use the loadb command to send a file over uart. We've used Teraterm to send files over kermit, but there are likely other programs that can do it as well.
- JC 09:57 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: Serial flash of u-boot-ubl.bin not working
- I don't remember when the u-boot-ubl.bin file is supposed to be used but according to the [[Reprogramming_a_Dead_Board]] guide, the u-boot.bin file that is output when building u-boot should be used with the sfh_OMAP-L138.exe tool.
- Hi,
I have a custom board without Ethernet (so far). The factory u-boot.bin works fine but I need the bootelf command upgrade. I cannot use uboot to update uboot because it uses ftp on ethernet so I am using sfh-OMAP-L138.exe to load...

- Hi Mike,
I'm using the pre-compiled reference image from your PCI Hard IP page. I didn't try to compile the project myself (although I suppose the result will be the same if I do so).
Thanks for all the support.
Alex - MW 08:44 AM MitySOM-5CSX Altera Cyclone V Software Development: RE: PCI-e Intel - System crash
- Hi Alex,
Sorry about this. My guess is that the FPGA project we provided is either not routing the PCIe interrupt to the same spot in the HPS that the device tree is configured for or perhaps not at all. The QSYS project would show ... - AL 04:45 AM MitySOM-5CSX Altera Cyclone V Software Development: RE: PCI-e Intel - System crash

The 3.12 image provided by Critical Link on the PCI Hard IP page seems to have been compiled without CONFIG_PCI_MSI=y, since when I try to load the intel driver with MSI interrupts compiled in I get

So I have tested both cards on a x86 PC with Kernel 3.12 and 3.18.9 and everything works as it should (using the same drivers, i.e. E1000E and XHCI).
I have also downloaded the pre-compiled image (PCIe Root Port with MSI) ...

Thanks for your support.
The boot pci-e related messages are (using Critical Link's images): - MW 09:57 AM MitySOM-5CSX Altera Cyclone V Software Development: RE: PCI-e Intel - System crash
- Yeah,
I am wondering if this error message might be an issue: - MW 09:53 AM MitySOM-5CSX Altera Cyclone V Software Development: RE: PCI-e Intel - System crash
- Hi Alex,
On the DevKit, we have found that the PCIe card edge is a little shakey without a mechanical mount (e.g., if the card tips forward and backward the PCIe signalling doesn't work well).
Are you running the same Linux version... - AL 09:15 AM MitySOM-5CSX Altera Cyclone V Software Development: RE: PCI-e Intel - System crash
