Hello,

I hope you are doing well.

The logs show that you are on U-boot.

To flash it, I suggest use the next command:

uuu -b emmc_all <Your file name>.bin-flash_evk

But on your logs, I can see that you are on U-boot.

Best regards.

Jorge.

[HelloMather]

thank for your reply.

yes i just only want to flash uboot, but actually uuu just send it to ram memory and finally report usb_init failed -22.

is that any place need to be configured or modifyed?

do you encounter similar problems or any directional suggestions can  be given?

thank you so much.

[HelloMather]

thank you so much.

yes i get the same error as before. so i enable the DEBUG macro in boot source and capture the more detail message info as attachments.

the difference between your print and mine are mainly:

......

switch to partitions #0, OK
mmc2(part 0) is current device
flash target is MMC:2
Net: eth0: ethernet@30be0000, eth1: ethernet@30bf0000 [PRIME]
Fastboot: Normal
Normal Boot
Hit any key to stop autoboot: 0

......

and mine are:

....

Command failed, result=1
Run fastboot ...
USB init failed: -22
Command failed, result=1

.......

could you help me analyze the reason for this difference?

[HelloMather]

here is my test bin

[JorgeCas]

Hello,

It is not needed to modify, using the command on my last post should be enough. 

If you want to try, you can flash U-boot with the next command and attached files:

uuu -b emmc_all flash.bin u-boot.bin   

But I think you will get the same result, also I will attach the log that I got.

Best regards.

Jorge.

NXP Jorge7u7, 

uuu -b emmc_all flash.bin u-boot.bin

It seems the build-in script will flash the u-boot to the use partition at offset 0. 

and burn flash.bin to the boot1 emmc boot partition.

And the i.MX8MP bootloader is not u-boot only, it is combined by aft, ddr firmware, u-boot with checksum to make sure its integration. 

It seems could not direction replace the u-boot in flash.bin, which is wrapped by imx-mkimage, because of the crc. 

To speak frankly, NXP Jorge7u7, your command is totally wrong. And the understanding of i.MX8MP bootloader(flash.bin) is totally wrong. 

But it is very basic knowledge for you NXP tech support.
