- ZM 07:53 PM MitySOM-A5 Software Development: RE: make_sd.sh doesn't take command line parameters
- Thanks! The boot script (both boot.cmd and the compiled boot.scr) does have windows line endings, which I think unfortunately appears to be confusing U-Boot. The config_pll script appears to be okay, which I think rules out a git hook ch...

- Hello Zach!!
I've uploaded mitysom-a5e-ref-dma.tar.gz (1.29G) - I've compressed the whole folder.
We didn't changed the design and scripts.
Thanks!!! - ZM 06:11 PM MitySOM-A5 Software Development: RE: make_sd.sh doesn't take command line parameters

The build seems to have partially worked since it was able to boot into U-Boot proper after the SPL, but past that it seems unable to load anything from the SD card for some reason.
Would it be possible for you to z... - MK 04:35 PM MitySOM-A5 Software Development: RE: make_sd.sh doesn't take command line parameters

Just to mention, we compiled mitysom-a5e-ref-dma project.
We've succedded to flash the SD card with Image and tried to run on MitySOM A5E board and getting following:

Did the script produce sd_card.img.gz instead? You're giving it flags for both gzip (@-g@) and zip (@-z@), and gzip should be taking precedence.
If so and you didn't want that, you could either run @gunzi... - MK 03:38 PM MitySOM-A5 Software Development: RE: make_sd.sh doesn't take command line parameters

The make_sd.sh script is intended to be run with bash, not POSIX @sh@. Could you please try running it as @./make_sd.sh@ instead of @sh make_sd.sh@ (keeping the rest of your arguments the same) and see if the errors are reso... - We are trying to build the sd card image using documentation from https://support.criticallink.com/redmine/projects/mitysom_a5/wiki/Building_sd_2531pro

I think you can remove the NFC pins and give it a shot.

In mainline linux, I found the following in qcs6490-rb3gen2.dts: - NO 07:01 PM MitySOM-QC6490 Software Development: RE: SPI bringup

- WE 04:19 PM MitySOM-QC6490 PCB Development: RE: 4V on 3V3-SOM!
- Unfortunately this cannot be addressed on the SOM as the SOM will hang if this voltage is dropped lower than 4V.
For future baseboard revisions there will need to be a regulator in between the SOM and the downstream components on this... - NO 04:06 PM MitySOM-QC6490 PCB Development: RE: 4V on 3V3-SOM!
- Thanks Will. The pins are tied directly to a power plane on my prototype boards, so I'll try breaking the connector pins as you suggest.
Will this issue be fixed in later versions of the SOM, or should I plan on adding a 3V3 regulator... - WE 01:07 PM MitySOM-QC6490 PCB Development: RE: 4V on 3V3-SOM!
- Hello Nathan,
The PMICs on the SOM support changing the output voltage of this pin. The idea was to have it at 3.3V but unfortunately the SOM hangs if this voltage is lower than 4V.
As a result we had to re-spin our development boa...

- Hello,
Why is 3V3-SOM outputting 4V? Is there a way to change this to 3.3V?
I see that the devkit schematic shows it as 4V, but the datasheet and Carrier Board Design Guide (and the name!) show it as 3.3V. Unfortunately I just rece...

- MF 05:27 PM MitySOM-C10GX Firmware: RE: CLKUSR - Oscillator Specs?
- Hi Sean,
The oscillator that is driving the CLKUSR pin is *KC2520Z100.000C15XXK*. Per the datasheet, this is a 30 ppm oscillator.
- Mike - What is the frequency tolerance and stability (in PPM) of the 100 MHz oscillator used to drive the CLKUSR pin on the SOM? I cannot seem to find this information in the SOM datasheet.
For context, my design contains an elastic FIFO us...

- Holden, TI wants to know if you are using the "VPAC/ISP camera functionality on your AM62A7". Presumably to determine if you need the dm_edgeai firmware or if you can get away with just the normal "ipc_echo_testb_mcu1_0_release_strip.xe...

I am having some difficulty bringing up a serial port that utilizes WKUP_UART0 pins. From what I understand, it is typically reserved for DM logging and is unusuable in Linux until it is disabled.

We currently have SBC and SOM Dev kit. We were told that they are equivalent from FPGA connections point of view, but I found out that's not completely correct.

- That matches what I'm seeing, although it seems your machine is much faster than mine. For me it's about 7 hours for a clean build, and 28 minutes for a rebuild.
- GG 02:36 AM MitySOM-QC6490 Software Development: RE: Long build times
- Hi Nathan,
We have similar experiences. Unfortunately we do not currently have a fix. We are building off of Qualcomm's methodology and there is a lot of complexity there that we haven't needed to dig into yet. We will update this is... - JC 01:26 PM MitySOM-AM62, MitySOM-AM62A, & MitySOM-AM62P Software Development: RE: Uart issue in Am62P

The issue was in the code. We have a function that returns an int, but the application was crashing within that function when running on the AM62P with Debian OS. However, it works fine on the AM62A BSP.

Please refer to the [[Configuring the QUP Ports (I2C I3C SPI and UART)]] wiki page which has recently been published for details on how to do this.
Let me know if you have any questions or issues.
