i.MX6SoloX eFuse programming, using U-boot

SLICE — Wed, 31 May 2017 02:23:12 GMT

Hello Yuri‌

Thanks a lot for your support.

I checked with the customer on your comments.

Actually, on the customer’s production line, they cannot use network connection.

Because the information you gave me is to use TFTP environment, they cannot use the solution.

Could you show me how to modify u-boot for remove final confirmation(key input 'Y') by user for programming eFuse?

Thanks,

Miyamoto

Hello,

You may find example of fuse command implementation at

git.denx.de Git - u-boot.git/blob - cmd/fuse.c

For NXP Linux BSP You may look at Chapter 1 (Porting U-Boot from an i.MX 6/7 Reference Board
to an i.MX 6/7 Custom Board) of i.MX BSP Porting Guide, Rev. 0, 10/2016, regarding NXP U-boot details :

The U-Boot code is now located at <build directory>/tmp/work/<machine>-poky-linuxgnueabi/
u-boot-imx/<version>/git, where <machine> can be one of the following:
• imx6qsabresd
• imx6qpsabresd
• imx6qsabreauto
• imx6dlsabresd
• imx6dlsabreauto
• imx6solosabreauto
• imx6slevk
• imx6sxsabresd
• imx6sxsabreauto

• imx7dsabresd
• imx6ul_14x14_evk
• imx6ull_14x14_evk

Have a great day,
Yuri
