ESP32-C3 OTA from buffer

[netanbi]

Hi i am using esp32-c3 program it with ota from HTTP request and everything work very good now i program a different project , i take hello world example and convert the .bin file to c file then i create header file with that "hello word" c file

this is the start of the .bin file in c just to explain how it look

ifndef BIN_FILEH

define BIN_FILEH

const unsigned char ota_buff[158432] = { 0xE9, 0x05, 0x02, 0x1F, 0x22, 0x03, 0x38, 0x40, 0xEE, 0x00, 0x00, 0x00, 0x05, 0x00, 0x03, 0x03, 0x00, 0x63, 0x00, 0x00, 0x00, 0x00, 0x00, 0x01, 0x20, 0x00, 0x02, 0x3C, 0xE0, 0x78, 0x00, 0x00, 0x32, 0x54, 0xCD, 0xAB, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x31, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,

the program enter to ota state but i received error ; E (25341) esp_image: invalid segment length 0x696e6920

}

please advice how i can fix that , because i see he enter to segment 0 but filed to continue

Are you pasting a C example to a Rust project? What are you trying to do, actually?
