Hello,

Please run the tool in verbose mode by using the following command:
sudo ./uuu -V -b emmc_all imx-boot-imx8mp-lpddr4-evk-sd.bin-flash_evk imx-image-full-imx8mp-lpddr4-evk.wic.bz2

After this, please share the tool output so I can see more information on what is going on.
Also, please share the serial terminal (Uboot) log.

Best regards,
Aldo.

Hello,

This seems to be a problem when using Ubuntu 20.04/libusb, unfortunately haven't found what is actually going wrong, more details here:
https://github.com/NXPmicro/mfgtools/issues/183

Some workarounds that have worked for other customers that you could try on your side are:
> Using Ubuntu 18.04 host PC
> Do not use USB Hub, connect directly to host PC
> Even connecting to a different USB port has helped in some cases

Please try any of the above if it can help you, if not please do let me know.

Best regards,
Aldo.

Hi, @AldoG 

I tried it again on Ubuntu 18.04 host PC without USB Hub.

However, its result was same.

I attached log.

Best regards.

My problem was solved with using next stable uuu(1.4.193).

However, I didn't understand which changes solved my problem.

Please, let me know.

Best regards.

Hi,

Glad to hear that it is now working, unfortunately is hard for me to say what actually fixed your issue since device got stuck at Run fastboot…. So, it could be some random USB issue.

Finally, from the release notes the bug fixes between those 2 versions are the following:

Bug fixes
Fixed 314 Corrupt image with larger transfer sizes at sdp(s)

Fixed invalid progress percentage in verbose mode
Fixed QSPI flashing script

Fix #180 support check getval return value

Best regards,
Aldo.
