Thread border router with S3 and C6
Posted: Tue Nov 28, 2023 8:39 pm
Hello,
I have custom board with ESP32-S3 and ESP32-C6 on it. I want to flash it with thread border router. I followed this tutorial: https://openthread.io/guides/border-rou ... ssif-esp32 and changed a few things.
I changed the target of OT-RCP from esp32h2 to esp32c6 and changed pins in `sdkconfig.ci.rcp` to:
CONFIG_OPENTHREAD_UART_PIN_MANUAL=y
CONFIG_OPENTHREAD_UART_RX_PIN=16
CONFIG_OPENTHREAD_UART_TX_PIN=17
and in esp-thread-br/examples/basic_thread_border_router I changed pins to:
CONFIG_PIN_TO_RCP_RESET=16
CONFIG_PIN_TO_RCP_BOOT=17
CONFIG_PIN_TO_RCP_TX=15
CONFIG_PIN_TO_RCP_RX=7
After flashing the firmware the esp is still restarting after a few seconds. The output is the following:
What could cause the problem? I'm pretty much stuck and don't know how to investigate the error further. Is it possible to run a thread border router with C6 instead of H2?
Thank you for your answers.
PS: here is a simplified schematic of the board:
