How to get all Software Versions (IDFGH-7573)

[franz-ms-muc]

Hello,

how to get Version Name etc.. from

• running Partition (that is easy, just look in startup.c)
• the other OTA Partition
• the Test Firmware
• the Factory Partition
• the Bootloader

also can one add some Fields in the code which are "reserved" spaces in the bin File, which can be set by a script, and later read by the code ?

Thanks,
Franz

For the first 4, I think esp_ota_get_partition_description does the job. Not sure about the bootloader.
As for the question, I think so.

+1 would also like to the be able to report the boot loader version to the cloud.

@franz-ms-muc There is an open feature request for getting the IDF version used to compile the bootloader: #8800. Please follow that ticket for updates.

For the rest, @KaeLL is right, esp_ota_get_partition_description should give you the structure with the required information.

also can one add some Fields in the code which are "reserved" spaces in the bin File, which can be set by a script, and later read by the code ?

If you add these fields during the compilation process (via rodata_custom_desc section), then yes. Overwriting parts of the binary after it is created isn't supported, because the hash of the binary image will become incorrect.
