hi,I am trying to update the u-boot of the warp7,I fallowed the exactly step in the: https://github.com/WaRP7/WaRP7-User-Guide/blob/master/04-Chapter/U-boot.adoc
the original u-boot information is：
U-Boot 2016.07-00091-ge6b4241 (Aug 22 2016 - 10:56:52 +0800)
CPU: Freescale i.MX7S rev1.2 at 792MHz
CPU: Extended Commercial temperature grade (-20C to 105C) at 47C
Reset cause: POR
Board: WARP7
DRAM: 512 MiB
MMC: FSL_SDHC: 0
In: serial
Out: serial
Err: serial
Net: CPU Net Initialization Failed
No ethernet found.
Hit any key to stop autoboot: 0
then i use the command: sudo ./imx_usb u-boot.imx
the newly u-boot infromation is:
U-Boot 2016.07 (Mar 03 2017 - 16:55:17 +0800)
CPU: Freescale i.MX7S rev1.2 at 792MHz
CPU: Extended Commercial temperature grade (-20C to 105C) at 51C
Reset cause: PORtop autoboot: 6
Board: WARP7
I2C: ready
DRAM: 512 MiB
PMIC: PFUZE3000 DEV_ID=0x30 REV_ID=0x11
MMC: FSL_SDHC: 0
In: serial
Out: serial
Err: serial
Net: CPU Net Initialization Failed
No ethernet found.
Hit any key to stop autoboot: 0
then i fallowed the comand:
=> env default -f -a
=> saveenv
Run the DFU command:
=> dfu 0 mmc 0
and sudo dfu-util -D u-boot.imx -a boot
then the u-boot showed the message:
#DOWNLOAD … OK Ctrl+C to exit …
then i powered off the warp7,put WaRP7 board into normal boot mode,reboot again,the updated u-boot information is :
U-Boot 2016.07-00091-ge6b4241 (Aug 22 2016 - 10:56:52 +0800)
