Hi,
Currently, I have working on i.MX 8M Quad Evaluation Kit. I have create one layer and add new machine in yocto. Now I try to flash evk board using below command.
sudo ./uuu -b emmc_all imx-boot-<machine>-sd.bin-flash_evk < custom bz2 image>
Output:
Success 1 Failure 0

Observation:
1. Evk not boot-up in internal boot mode
2. I have flashed pribuilt image in evk but not boot-up in internal boot mode.
Question:
Please give the suggestion for this issue.
Which version of BSP are you using? Are you using the demo images or images you build yourself?
Hi Rita,
First I have flashed the (LF_v5.4.y-1.0.0) demo image in i.MX8M Quad Evk and board boot up successfully.
After that i have create custom layer in yocto and build the custom images.
I have flashed the custom images but system doesn't boot-up. After that I have flashed demo images but board not boot-up.
For the demo images can work, we have tested on our board. You make sure the boot mode and boot command are right. You can retry it.
