imx8mn flashing a image after bitbake

dear team,

My customer has tried to flash the images that were created from the bitbake using uuu tool.

Tried two commands:

sudo uuu -b emmc_all imx-boot-imx8mn-ddr4-evk-sd.bin-flash_ddr4_evk imx-image-core-imx8mn-ddr4-evk.wic.bz2

sudo uuu -b emmc_all imx-boot-imx8mn-ddr4-evk-sd.bin-flash_ddr4_evk imx-image-core-imx8mn-ddr4-evk.tar.bz2

 

in the debug console of IMX8 I see the following:

 

it any key to stop autoboot:  0

## Checking Image at 43800000 ...

Unknown image format!

Run fastboot ...

 

Can you please advise what exactly am I doing wrong?

Secondly, if you could explain a bit about each file inside the deploy folder (see attached log file)?

Thanks in advance 

KR,

Shai

did the customer try the demo images? did their board boot up demo images successfully?

Hi @joanxie,

No, the UUU did not flash due to the following error: 

Unknown image format!

Can you please advise if the commands are correct (for flashing the imaging into the emmc)?

sudo uuu -b emmc_all imx-boot-imx8mn-ddr4-evk-sd.bin-flash_ddr4_evk imx-image-core-imx8mn-ddr4-evk.tar.bz2/*

also, can you please explain why there are so many files in the deploy folder and which one if the final "bootloader"?

Waiting for your feedback, Thanks a lot

KR,

Shai

Hi @shai_b ,

You can add option -v to see the progress of the flashing :

sudo uuu -v -b emmc_all imx-boot-imx8mn-ddr4-evk-sd.bin-flash_ddr4_evk imx-image-core-imx8mn-ddr4-evk.tar.bz2

And sometimes, flashing issues are caused by the bad-quality USB cable.

Best Regards,
Khang
