Hi Huaping Tan,
Attached compiled binary(IAR). I just use Jlink/IAR to download project, It’s OK to run. Download via CycMax and Jlink should have no difference.
Pay attention to this on AN5219:
- 1.

- 2. TerTerm baud rate setting must be 115200.
Also, please provide me customer’s name, product and LTR, thanks.
