JaySolar reacted to Coulomb in INFINISOLAR 3KW PLUS firmwareI had a quick scan of the latest of those firmwares, because that's what I do 😎
Alas, while the main firmware is TI C2000 DSP, I could not find any commands that I recognise as carrying a firmware version number; it seems to leave that sort of thing to the "slave" processor.
I don't even know what chip the slave processor is. The firmware file is in Motorola format, but it's more than 64k in size, so it's not the usual 8-bit Freescale HCS08-like instruction set. I see standard looking commands in there (not even "secure" commands starting with the '^' character), but not knowing the chip used, it's hopeless guessing what version it is.
Astonishingly, there doesn't seem to be any clue what the firmware versions are! The only slight hint is "with Pylontech Li battery support".
