My device is OTT, and every thing is fine before I did " imxotp blow --force 6 1; :imxotp blow --force 6 2;"  imxotp read 6, I got 3.


Then I power off the device, and power on again, The device can't boot again.  I change Bootmode[1:0]   to 01, the serial download via usb, The Device always stay in this mode:

Bus 002 Device 015: ID 15a2:0054 Freescale Semiconductor, Inc. i.MX6Q SystemOnChip in RecoveryMode

even  I run "sudo ./imx_usb ./u-boot_ok.bin"

No "_" environment variable

argc == 2, argv == 0x7fffc06491b8

base == 0x608200:./imx_usb

trailing slash == 0x608201:/imx_usb

conf_path == ./

config file <./imx_usb.conf>

<<<179492, 179492 bytes>>>

jumping to 0x27800400

 

and It goes to serial download via usb mode again, But I can't run imx_usb again.


anyone can tell me what's wrong with my fuse map?


Does anyone has the fusemap of mx6q?


How Can I turn this brick into normal mx6q device?
