NRF52833-B-QIAA off board using ELNEC Pogrammer

[Fabio Alves]

I'm trying to programm the NRF52833-B-QIAA off board using an Elnec programmer model BeeProg2, but as the revision B of this MCU comes from the factore with APROTECT ENABLE, I don't know how to DISABLE the APROTECT and configure the programmer in order to leave the IC unlocked.

According to the manufacturer, it is necessary to change the bits in the UICR file, which I do not know how to do.
Could someone please just send me the already edited UICR file so that I can load it into the programmer in order to try to unlock the IC ?

Hi

What exactly are you trying to program onto the board here. I'm assuming it setts the APPROTECT enable. My colleague Vidar explains in great detail in this ticket how to make sure APPROTECT is disabled on your board.

To get it in an unprotected state in the first place, start by doing an nrfjprog --recover to recover the device into an "open state".

Best regards,

Simon
