JC 06:20 PM MityDSP-L138 (ARM9 Based Platforms) PCB Development: RE: Munti-function OMAP pins
Note if you developing a custom baseboard, I'd recommend sending it to support@criticallink.com to have it reviewed.
Also review the https://www.criticallink.com/wp-content/uploads/2014/01/MityDSP-L138-Carrier-Board-Design-Guide.pdf

Hello,
I would like to use the SPI1 on the OMAP with two separate devices are the pin functions in the critical link datasheet table 1 exhaustive?
For instance, could I use pin 61 as SPI1_SCS[5]? The OMAP documentation has it liste...

JC 03:43 PM MitySOM-AM62, MitySOM-AM62A, & MitySOM-AM62P Software Development: RE: Error building kernel and rootfs on host having Ubuntu 23.04 with docker
Hi Rohini,
I'm not sure why this happens, however especially when all the failed packages are "native" packages and the errors always seem to mention missing files.
I've had good luck cleaning and rebuilding just the failed package...

At this point in the boot, we've already read the eeprom and the pmic is all setup. The i2c0 bus becomes a lot less crucial from the SOMs perspective. I don't think an i2c issue would c...

Jonathan,
Thanks for taking a look at the logs.
This is an issue we have been having in parallel to the I2C issues. Good news is the updated kernel does seem to experience much less I2C hanging than previously...now I believe the o...

Jonathan,
Apologies on the delay, we've had most of the systems tied up in-use for the past few weeks but I was able to grab some UART captures this morning.
I've attached 4 files - BOOT1-4. BOOT1 did not boot successfully...seems ...

Sorry if I wasn't clear. The caps are optional. They might help in a worst case situation, but for most designs they are overkill. Leaving one off won't be a problem. If you are doing a design and have the option to put them on, it w... David Rice

AF 11:34 PM MitySOM-5CSX Altera Cyclone V PCB Development: RE: MSEL[4] and return current cap...
Hi David,
I understand that, but the eval board only has them on MSEL[3:0] and does not have one on MSEL[4].  So, should there be one on MSEL[4] on any design using the MitySOM or not?
Thanks,
Austin

DR 07:38 PM MitySOM-5CSX Altera Cyclone V PCB Development: RE: MSEL[4] and return current cap...
The intention of the caps to ground on these signals is to allow some high frequency ground currents from the SOM I/O's going off-SOM to have additional paths to ground, since the MSEL signals (and other listed signals) are essentially D... David Rice

The dev board has MSEL[3:0] with 1000pF caps, and MSEL[4] does not have a cap, unless I missed it. In the design guide:
7.4 Return Currents
The module’s edge connector has GND connections distributed along the interface pinout to ma...

Hi everyone,
For anyone who is reading, I have figured it out and I hope this will help you.
The U-Boot is running a script, see the bootcmd below

Part number 91115A501 is a 3/8" size standoff (1/8" tall, 4-40, hex). The one on the deb board I have is 1/4" size, which is part number 91115A160.
