utest nvm user space programming

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,

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

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.
