idcode for lpc812 (bug ?)

Post by krbonne » Thu Nov 16, 2017 2:33 pm


Has somebody already used openocd with a NXP lpc812?

It looks like the idcode for that chip is not correct in openocd (0.10.0). Openocd seams to expect 0x0bb11477, while the chips I have return a different idcode: 0x0bc11477

I've tried with two different types of chips: the DIP8-version of the LPC810 and TSSOP20-version of the LPC812 with the same result.

Before I file a bug-rapport, can somebody confirm / deny this?

BTW. I got openocd 0.10.0 working by adding this line as 2nd-last line in target/lpc8xx.cfg :
set CPUTAPID 0x0bc11477

Cheerio! Kr. Bonne.
