update firmware from SPIFFS esp8266
Posted: Mon May 29, 2023 12:21 pmHi to all, Im using esp-01S 1Mb spi memory and I found this link https://arduino.stackexchange.com/questions/77164/flash-esp8266-from-spiffs-filesystem on how to update firmware from SPIFFS. I tried to use this code in the esp-01S using arduino IDE 1.8.19 (I upload to SPIFFS the Blink binary and used this code to flash de memory of the ESP-01S).
Checking the serial terminal I read a lot of garbage and I see this part:
and the esp-01S doesn't do anything else. A few questions:
1)This is possible with the esp-01S?
2)why this code doesn't work with the esp-01S?
3)Why this sentences uint32_t maxSketchSpace = (ESP.getFreeSketchSpace() - 0x1000) & 0xFFFFF000;?
maxSketch return the size of the skecth but don't understand 0x1000 and 0xFFFFF000. Those a flash sectors? How can I know where to flash the new binary?
4)Is there an Update.h file that I can use withoout using other libraries to be able to update firmware on esp-01s?
Thanks
Gaston
