TLSR9218H can't flash code the 2nd time
Jun 22, 2023 18:09
With the telink TLSR9218H chip, I flashed the code the first time but it failed to flash the next time.
I'm using BDT software version 5.7.2.
Schematic pinout:
PA5 connect to 3.3V
PA6 connect to SWM

Hi，
Normally, we should use PA7 as the hardware SWS without software initialization. However, 9218h is a security chip that shields PA7 and uses PA6 as the SWS. This pin requires your software initialization. When your program does not properly initialize PA6 as SWS, it will cause unable to download the program. Please contact your FAE for support.
