You can override components on a per-project basis. In your project directory, make a PROJECT_DIR/components/bootloader directory and copy the contents of IDF_PATH/components/bootloader to here. This bootloader component will be used in preference to the IDF one. Thats a brilliant feature - well done

Hi Angus, Even if the ota image is not present at all and you set the OTA data to say boot from that OTA image - the bootloader will attempt to boot from it and then fail verify and then do nothing.

Hi Guys, @ ESP_igrr @WiFive, Thanks for the help so far . I got OTA working quite painlessly so great job there Espressif.

Hi WiFive, Thank you for the reply. We dont have a button on our esp32 module that can be used to have a failsafe boot to factory option. Is there any other way you can think of that we can have a failsafe OTA mechanism - that is in case you load an application that has the updating ability broken ....

can anyone shed some light ? @ESP_igrr

Hi Espressif, I am trying to get my head around the OTA procedure so I can implement it for our product . I have looked at the example readme file. The OTA as it is, is not really suitable for us as our product will be the AP rather than a station. This is my understanding of how the example works, ...

Works like a charm - thank you for the quick response

Hi,

How do I perform a sofware reset on esp32 ? I tried REG_WRITE(RTC_CNTL_OPTIONS0_REG, RTC_CNTL_SW_SYS_RST); But after reset it doesnt run again?
