USB problem using uuu tool to program imx6UL

logman — Sat, 08 Jul 2023 09:13:57 GMT

Hello,
I have a problem flashing my imx6UL device using the UUU tool. I'd appreciate some help please.

I am powering-up the chip with the BM1 pin pulled low as required.

The uuu tool shows the following:

$ ./uuu.exe uuu_smartcom.auto
uuu (Universal Update Utility) for nxp imx chips -- libuuu_1.5.21-0-g1f42172

Success 0 Failure 1

3:1 1/ 0 [Failure open usb device ]

This is an extract from the uuu_smartcom.auto script:

uuu_version 1.4.193

FB: ucmd setenv bootargs ${bootargs} ${mtdparts}
FB: acmd ${kboot} ${loadaddr} ${initrd_addr} ${fdt_addr}

The uuu tool executes all of the above commands OK, then it hangs on the 'FB: acmd' command before it reports 'Failure open usb device'.
When I run my uuu script, the device shows the sequence copied below (from --- START OF TERMINAL TEXT) on the Putty COM1 linux terminal.
The terminal output indicatse that /dev/utp fails to appear in the device.
My machine is Windows 10, and I have seen the same behaviour when executing on WSL Ubuntu.
I have updated the utp USB Windows driver to 6.1.7600.16385 from libwdi.

My colleague has successfully run the same process on his setup, using the same target hardware and the same firmware and uuu setup.
I have run this process successfully last month, but it would appear that something is going wrong with the USB access now.

I have looked at various forum posts, including https://community.nxp.com/t5/i-MX-Processors/IMX8-board-recognized-as-SE-blank-815/td-p/1174462

Can anyone suggest what to try please? I'm out of ideas.
Thanks,
Tom.

Fixed!!! I used the zadig utility to change the utp USB driver from "WinUSB (libusb)" to "libusb-win32". The uuu tool runs smoothly now
