Are FBK: commands with the uuu tool supported on i.MX6 ULL ?

[dallasfoley]

I can successfully load u-boot, .dtb, zImage and initramfs with the uuu tool's SDP: commands from my linux host.

However, I'm not sure how to run FBK: comands. I just get 'Wait for Known USB' as a response.

Hi Dallas

yes it is supported, one can look at documentation

UUU default support protocol list · NXPmicro/mfgtools Wiki · GitHub 

https://github.com/NXPmicro/mfgtools/releases/download/uuu_1.2.0/UUU.pdf

I can't seem to get the FB: commands working for u-boot.

I have the fastboot command running in u-boot and my usb device shows up on my host, but the command fails.

./uuu u-boot-dtb.imx

./uuu -s

U>FB: ucmd help
1:2>Start Cmd:FB: ucmd help
New USB Device Attached at 1:2

Bulk(W):LIBUSB_ERROR_TIMEOUT

one can look at example_kernel_emmc.uuu included in

Linux Binary Demo Files - i.MX 6UltraLite, i.MX 6ULL, i.MX 7Dual
