Hi
I'm trying to build the uboot image from source and download to the iMX8M EVK. I'm starting from the latest 'linux-sumo' 4.14.78 source found here:
https://source.codeaurora.org/external/imx/imx-manifest/tree/?h=imx-linux-sumo
Everything builds as expected and I can produce a "imx-boot-imx8mqevk-sd.bin-flash_evk" file, which I have selected with the manufacturing tool cfg files (I have previous experience of this from work on iMX6).
The processor powers up and I can see the HID device on USB. However when I click start on MfgTool, it does something, and then goes Red to indicate failure. The Console shows the processor starting boot, doing DDR4 training, and then it stops on:
Trying to boot from USB SDP
SDP: initialise...
SDP: handle requests...
The boot does not progress beyond this. Why?? I notice that the USB device changes from the 1fc9:012b NXP device to a 0525:b4a4 Netchip Technology device. Why is this?
I can successfully boot the imx-boot image provided with the mfgtool image I have downloaded, so I know my setup is good (this image boots to uboot console, as I expect).
Why does the 'out of the box' image not work for the eval board? Is this an issue, or am I doing something wrong?
Note I have also tried booting the image using the imx_loader toolcloned from github, with much the same result.
Thanks.
