Accessing OCOTP fuses in linux-fslc 4.1.7

Hi all,

I need access to the OCOTP-fuses of i.MX6 from Linux. Read access is currently sufficient.

I see that read support is in the 4.4 and 4.6 branches of linux-fslc, but I had no success porting it to our 4.1.7 tree.

I also tried to include the fsl_otp driver from wandboard-linux (linux-imx-wandboard/fsl_otp.c at master · wolfgar/linux-imx-wandboard · GitHub ). Since we based our board on the wandboard, we originally had this enabled, but now it is not there when we need it.

Are there other options for reading the fuses from Linux?

Does anyone have a patch that applies on 4.1.7? Since we have a bunch of custom patches I would prefer to stick with 4.1.7 for now if possible.

Best regards,

Mikkel Holm Olsen

Hi Mikkel

4.1.7 tree is not supported on nxp linux releases, one can try

to post this on meta-fsl-arm mailing list, so that someone familiar with

wandboard could try to assist you.

Best regards
