IMX6ULL NAND flash boot failed

allonli — Tue, 24 Mar 2020 03:45:27 GMT

trying to burn image to NAND FLash on IMX6ULL platform by mfgtools_4.1.15,

now stuck on "No device connect".

log info show as below on the left, halted at "configfs-gadget gadget: high-speed config #1: c",

I try the same operations on IMX6ULL EVK demo board, while the log info show on the right. (IMX6ULL EVK no NAND flash on board)

it seems the utp device have been found, but UTP cammand can not receive or can not excute?

I set USB OTG1 ID floating, and also let dr_mode=peripheral

what could be the reason?

Hi Allon

reason may be that usb is not working on custom board

one can test usb (both host and device mode) using imx-test package,

folder mxc_usb_test

Best regards
igor
