Cc-wmx93-kit getting started not loading

Embedded Devices
1

I just today received my anticipated cc-imx93-kit and started to go through the step by step to get started.
When I boot the board and stop u-boot to load the fw image, I get the message that install_linux_fw_sd does not exist.
Looking at the u-boot information I find the u-boot is version 2022.04 which is not what the guide states.
I also see the device is an A0 device.

I already used diskpart to get the sd formatted as FAT, but still no luck. I also tried to use my linux VM where minicom connect fine and lets me run ‘fastboot 1’. I am assuming that it should stay in that position but the sh script just waits for a USB device to appear.

Is there an alternative way to get fw loaded?

EDIT:
I just saw that the fastboot 1 command creates the USB OTG and can be connected to my VM. So far so good.
Now the VM creates this message when starting to load using fastboot: 1:1 1/ 1 [Bulk(W):LIBUSB_ERROR_TIMEOUT ] fb: ucmd setenv stdout serial,fastboot

EDIT2:
I ran the following UBOOT command and think I need to figure how to run from mmc 1.

=> ls mmc 1

      668   README.txt

10 file(s), 1 dir(s)

=> run install_linux_fw_sd
## Error: "install_linux_fw_sd" not defined

How do I get it to run when it does not behave as the guide expects?

I also tried to use my linux VM where minicom connect fine and lets me run ‘fastboot 1’. I am assuming that it should stay in that position but the sh script just waits for a USB device to appear.

You would need to transfer a fastboot USB device from host to the VM. it can be tricky.

if your board is still booting use the second half of the getting started guide:
https://www.digi.com/resources/documentation/digidocs/embedded/dey/4.0/cc93/yocto-gs-program-fw_t.html#download-the-firmware
Scroll down to the section:

Program the firmware using uSD card

If this doesn’t work, please provide logs. For faster response please open a support case by sending an email to tech.support@digi.com

Hi LeonidM

Reading my edits will show that I have tried that already, and that run install_linux_fw_sd fails

I am thinking maybe running mmc dev 1; update uboot imx-boot-ccimx93-dvk-A0.bin will make the update so that the install will work?

yes, please take a look at Recover your device | ConnectCore 93
scroll all the way down to Re-program the bootloader from the microSD card

Re-program bootloader from microSD card
Place the U-Boot binary inside a FAT-formatted microSD card.

Insert the microSD card in the board.

Run the following command to update U-Boot into the eMMC:

update uboot mmc 1 fat <u-boot-filename>.bin
5

If looking at my boot log, do you agree that my device is an A0 revision please?

6

yes it is A0

=> run install_linux_fw_sd

Error: “install_linux_fw_sd” not defined

Try those commands instead:

=> fatload mmc 1 $loadaddr install_linux_fw_sd.scr
=> source $loadaddr

7

I now tried your command suggestion and it updated u-boot but failed at a bootcount command and seem to have left out the linux install.

=> fatload mmc 1 $loadaddr install_linux_fw_sd.scr

I now did, however, do the run install_linux_fw_sd command and it installed Yocto this time round :slight_smile:
