[upload] Error 2 with esp8266 ESP-07 board #193

#1

I use VSCODE to create project. I create a project and select ESp-07 board and ESP8266 RTOS SDK framework then create a main.c file in src directory and copy content of main.c file of esp8266-rtos-sdk-blink example to my project main.c file. it compile successfully but when i want to upload it to my board following error occur :

*** [upload] Error 2

I test my board with Arduino framework successfully.

Thanks you

You’ve configured it as a board with 4MB of FLASH, but the bootloader as auto-detected it as

You could correct that by changing the flash size configuration script used via your project configuration platformio.ini… i.e.

build_flags = -Wl,-Teagle.flash.1m.ld

Thank you
I copy eagle.flash.1m.ld file from Arduino sdk (because there isn’t such file in rtos sdk) to src directory and add flag then build project now following error occur :

*** [.pio\build\esp07\firmware.elf] Implicit dependency C:\Users\MrTavakoli\.platformio\platforms\espressif8266\builder\eagle.flash.1m.ld' not found, needed by target.pio\build\esp07\firmware.elf’.

I try with eagle.app.v6.new.1024.app1.ld file of rtos sdk framework and same error occur.

Oh bugger…you’re using the ESP8266 RTOS SDK and I’m giving you instructions for the ESP8266 Arduino framework! :man_facepalming:

Ok, the RTOS linker scripts are

in .platformio\packages\framework-esp8266-rtos-sdk\ld

so see if it works with:

build_flags = -Wl,-Teagle.app.v6.new.1024.app1.ld

(you shouldn’t need the file in your project dir, it’s framework supplied).

If that doesn’t work, someone more familiar with the ESP8266_RTOS stuff will have to help you out.

Thanks
It don’t work :frowning_face:

#6

I use esp01-1M board instead of esp07 board and compile then upload to esp07 board successfully.
again change board to esp07 and add

board_upload.maximum_size = 1048576

to platformio.ini file and compile and upload to esp07` board successfully.
I found 1048576 value from esp01_1m.json file.

Oh, nice! So it looks like the size constraint came from that, not the memory layout file… Good to know! Thanks for sharing! :slight_smile:

I also had the same problem, I was using esp32S3. How can this microcontroller developed with platformio solve this problem?
