Thanks Terry for your response. Sorry for not having seen this thread in many time, I just simply put them in a drawer and moved to another devices.

Time today is gold.

Thank you again, for your gold.

Hi, I am trying to do my own firmware for T-RSC3. I bought one months ago, I executed the example, ok. Then I just simply wanted to create a new project using ESP-IDF samples, for doing OTA. After flashing it, the unit became bricked. The device never connects to the PC, no serial port. I'm using Linux, but I tested it in Windows. The board is death.
The vendor refund me, and I purchased two more units (I need 485 in my project, and your device fits very well). Then I executed the example code from Lilygo, ok. Then I flashed another example (totally different from the OTA example months ago), which caused the unit to reset. After a while, in the serial line there was garbage. After unplugging the unit, it's bricked the same way.

No physical damage, different projects, and same result. Is the hardware so weak? How could this happen and how can I prevent it to happen? Have you seen it? Are you planning to fix it?

Regards.

Tx
