STWLC38: GUI connect No response

jbie · ‎2024-03-27

Hello,

I have a custom board with a STWLC38JRM.

Everything was fine and I was able to flash it with STSW-WPSTUDIO v1.8.4 through the dev board STEVAL-WLC38RX and FT_SDA/FT_SCL/VBUS/AGND pins.

I try to make some test and I disabled internal overtemperature protection in config. After that, I'm not able to connect to the STWLC38JRM again. I tried the chip with "RX" and "Empty" in WPSTUDIO without any success. I already had a similar issue and the chip was in Empty state.

Is it possible to "factory reset" the chip without I2C link ?

Thank you.

HI

We only use I2C to update fw, please make sure FT260 dongle is ok ,

about GUI connect issues, i suggest you use

https://github.com/STwirelesscharger/STSW-WPSTUDIO/blob/main/STSW-WPSTUDIO%20V2.1.0.exe

a1_wlc38_downfw.bat to download fw automatic.

Also please check GUI log and post it if still fail.
