ESP32-S2 Invaild Header / Timed out waiting for packet content error
Posted: Wed Mar 08, 2023 9:10 am
Hi,
i have designed my own board for the ESP32-S2. Here you can see the corresponding schematic.
When I apply voltage to the ESP32-S2 I get the following output via UART.
The real problem is that i can not flash the module. To flash the module i first put the ESP32-S2 into download mode by pulling the GPIO_0 to GND and meanwhile the CHIP_PU to GND. That this works i see at the UART output:
ESP-ROM:esp32s2-rc4-20191025
Build:Oct 25 2019
rst:0x1 (POWERON),boot:0x0 (DOWNLOAD(USB/UART0/1/SPI))
waiting for download
If i now want to flash the FW i get the error that you can see in the picture.
Does anyone have a solution how i can flash the module?
