I have a commercial device containing a JN5169. I can program it, but can't read it, although no read protection is set.
I always chalked this up to some kind of read protection. However, now I purchased some 'empty modules', and these behave exactly the same. Why?
The read fails at 0x200.
I am using these devices now:
I can flash them, but then it appears like stale data in the EEPROM is messing things up. However, I can't read them or erase the EEPROM.
When using the production flash programmer to erase the eepromp, either full or pdm, i get:
Error erasing EEPROM: Read error loading extension binary into RAM
Just flashing them without verifying works, and the output I get then, is the output I wrote into the application for it, so it is running the new version of software then.
However, when I'm trying to program and verify:
Error: Read error reading Flash at address 0x00000200
I'm using the production flash programmer build 1365. I have also tried flashing from Beyondstudio, this works, but also gives the verification error.
All userdate fields are set to 0xFF.
