[sef]

I'm trying to flash bootloader(imx-boot) and image(.wic, created with yocto) to EMMC with UUU tool but stucking after wrote "imx-boot".

UUU and u-boot output: pastebin.com/1BFrTJvQ
also, u-boot config: pastebin.com/snxCVxA1

Hello,

I hope you are doing well.

Could you please share the command that you used on UUU?

You need to flash:

<Your file name>.bin-flash_evk

<Your file name>.wic.zst or <Your file name>.wic

For example, here is the command to flash Linux 6.1 on i.MX8MN EVK:

uuu -b emmc_all imx-boot-imx8mn-lpddr4-evk-sd.bin-flash_evk imx-image-full-imx8mn-lpddr4-evk.wic.zst

Best regards.

Jorge.

@JorgeCas sudo uuu -v -b emmc_all imx-boot-coral-dev-emmc.bin-flash_evk test-image-imx-coral-dev-20230620055703.rootfs.wic

Hello,

Your board is on serial download mode? You can confirm it with:

uuu -lsusb

With the board in serial download mode and flashing the files mentioned on the last post should be enough to work correctly.

Did you try with the process on the official Coral Dev Board web page? It is listed on section "2: Flash the board".

Best regards.

Jorge.

@JorgeCasi mean, "2: Flash the board" works not UUU.
