Re: Crash when using stack on external PSRAM
Flash writes aren't supported from tasks allocated in the PSRAM as it uses the same SPI-bus. Queue writes and use other task to actually write them.

Re: Using ULP on ESP32-S3 while main cores are awake.
Had the same idea before. You could use a share register and counter to check if the main cores are still running. But the ULP has no means to execute a reboot/reset. It can just exit it's running state back to the point the ULP started and the core task stopped.

Re: How to set UART xon xoff characters?
The struct is used in the uart.c file when calling the SW Flow Conrol function. esp_err_t uart_set_sw_flow_ctrl(uart_port_t uart_num, bool enable, uint8_t rx_thresh_xon, uint8_t rx_thresh_xoff) { ESP_RETURN_ON_FALSE((uart_num < UART_NUM_MAX), ESP_FAIL, UART_TAG, "uart_num error"); ESP_RETURN_ON_FALS...

Re: ESP32 WPA2 Enterprise Connection via Identity and Certificate
I don''t believe esp32 supports networks with an authentication website after connecting to the wifi. The other network with wpa2-enterprise PEAP authentication should work. You will need to know the following before connecting: PEAP identity (can be the username or device mac address) PEAP username...

Re: ESP32 WPA2 Enterprise Connection via Identity and Certificate
Enable the debug log on mbedtls, lwip and WiFi to see any errors during authentication. This worked for me and I could see that there was insufficient heap to validate the customer ServerCa.crt upon handshake. Customer used quite a large certificate of 20kb. Also make sure the identity is set the wa...

Re: Cancel Http client data download
I'm still using the same method with the 15s timeout:
If I'm calling the "esp_http_client_close(evt->client);" function, the download stops without the HTTP_EVENT_ON_FINISH (no problem) but also after timeout of 15s.

Re: How to fill a a flash partition with files/data
I believe that the only way to populate the internal flash fatfs partition is to write files from the ESP to the partition. The fatfs filesystem is useful for reading SD-Cards connected to the ESP as these are compatible with other operating systems such as Windows. I'm using the SPIFFS storage myse...

What's your partition table? Mark that the app partitions need to be aligned with 0x10000 Can you set the bootloader logging?
