Hi everybody,

I have a (hopefully) simple question. We have a custom board with i.MX6ul controller, a JTAG connection and a ARM ULINK pro device. 

Is it possible to program the eFUSEs via JTAG with the ULINK pro device and if so, what software is used for that?


I know that it is recommended to use the NXP U-Boot software to program the fuses and that case is well tested and functional with our hardware - but we have use cases where we need to use the raw JTAG without UBoot already running on the device and without the USB-Bootloader and MFGTools.

Is that possible and what software is used?

Thank you guys and regards,
