Default bootloader sdkconfig ? #626

Closed Arlaz closed 2 months ago

Arlaz commented 2 months ago

Hello 👋 I’ve been struggling to make my project work with WiFi and a custom bootloader I need.

After many tests, it appears that my code runs correctly when using your « build by hand » espflash bootloader.

Would you mind sharing what modifications you made to it ? And / or the sdkconfig.default files you used with esp-idf to build your bootloader ?

Thank you for this project !

Is it an std or no_std project? If it's an std I would suggest using cargo-espflash so it uses the bootloader/partition-table generated in your esp-idf project, see https://github.com/esp-rs/espflash/tree/main/cargo-espflash#bootloader-and-partition-table

The bootloaders shipped with espflash (https://github.com/esp-rs/espflash/tree/main/espflash/resources) are built using the default sdkconfig, no changes and using an example from the ESP-IDF version that we select.

It is a no_std project, that's why I find this behaviour weird. I will try to make it work with a bootloader based on the same commit as yours.

Thank you for your answer !
