OK, if I change resistors to 15k instead, then now it always give me random chip id – my guess that now cc2531 cannot change internal capacity of the pin...
using 50k and 100k resistors it worked 🎉 probably internal pullup resistors are different chip to chip. now I'm able to read the flash
and I also write succeed. cheers! what is recommended way to make this knowledge shared? should I PR with just a note in readme or should I replace schematics, etc?
yes, I mean them. ok I can do that. Actually I had 50k/100k only for DD. DC and reset I drove with 15k/30k resistors to be extra sure target device...
please wait a bit. CC2531 is flashed and working perfectly, but CC2541 seems to be recognized wrong (#29)
All fine. Added more information in the troubleshooting section
I was able to do the thing using 50k and 100k resistors on DD line and 1.5k and 3k resistors on others. Please try too
BTW, DD is 2.1, and DC is 2.2. According to your schematics, you have it reversed
