is there a way to program utest user space(OTP data) by using jtag direct flashing?

just like how we flash the pflash and dflash?

Hi @pasa_kevin_y 

Yes, it is possible. It depends on your tools. If you have Lauterbach debugger, you can use simple script which I shared in this post a few days ago:

Thanks, it looks like the debugger load a driver to RAM and it plays the magic.

It should also follow the reference manual to program through the registers.

Hi @pasa_kevin_y,

you can use lauterbach cmm script to write data into UTEST area.
