Testing CC2531 about cclib HOT 9 OPEN

the chip is being detected properly (same as in the reply above), but when flashing it gives out the following error on MacOS 10.13.4 for me:

ERROR: Flash verification error on offset 0x0000

INFO: Found a CC2531 chip on /dev/cu.wchusbserial14110

Chip information:
      Chip ID : 0xb524
   Flash size : 256 Kb
    Page size : 2 Kb
    SRAM size : 8 Kb
          USB : Yes
Sections in CC2531ZNP-Pro-Secure_LinkKeyJoin_mod.hex:

 0x1ff6   10 B 
 0x3fff0   1 B 
 0x2000   239616 B 

This is going to OVERWRITE the chip. Are you sure? <y/N>:  y

Flashing:
 - Flashing 4 memory blocks...

    Progress 0%...  ERROR: Flash verification error on offset 0x0000

Any idea what can it be?

I bought one of the sticks as well and it did not work for me either. What finally let me flash it was https://github.com/RedBearLab/CCLoader on windows with prebuilt exe, arduino leonardo and a level shifter (not voltage divider) to safely interface with the stick.

I am not trying to discourage using CCLib, just that this might help get the ball rolling.

Works fine here on macOS 10.13.4, with a Arduino Due (so no voltage divider, and the native USB port with SerialUSB).

I understand this post is few months old but I've just hit same issue as @balonchiks. Solved it by adding
--erase at the end of cc_write.py command (I believe -e would also work as it clearly says it in the official instuction. Flashed CC2531 with Arduino Uno with no resistors.

Hi together! How did you wire your UNO? If I try to run the cc_info.py, I get only "No chip found. Check your connection and/or wiring". My CC2531 gets green for a short time. But nothing else happen :(

Where did you get the bin from?

Where did you get the bin from?

It's right there, in a folder named Windows

How and which pins did you use with your Arduino Due and the CC2531?

from cclib.

@balonchiks I was able to workaround this by lowering UART speed to 9600baud. Dunno why this worked ¯_(ツ)_/¯
