Check MCU type at start

[3djc]

Given the increased pressure on MCU sourcing, it becomes more likely that similar, or very similar radio get available with different MCU. This is already the case with TX12 and TX12-MK2, it will become more with upcoming T-Lite with F4 MCU.

On F2 hardware, F4 firmware do not start, but on F4 hardware, an F2 firmware starts and can appears to be running, when all timers and such are completely off, which can create great confusion.

This prevent running the firmware on MCU they where not compiled for. It includes all currently used MCU, as you never know whats comming

I would've made the text "Bad MCU" instead of "WRONG MCU" imo

[pfeerick]

But bad can also be interpreted as "faulty"... so we'll then get support requests of "I updated EdgeTX and now it says my MCU is faulty... did I break it?" Even though this is specifically aimed at the wrong MCU for the target... it could be argued that "Wrong Firmware" (hm... would "Wrong FW" be enough?) is a bit more on the nose.

[voltangle]

Good point! But at least I would've liked it without CAPS, so that instead of "WRONG MCU" it's "Wrong MCU"

Don't you start... the translators are going to be after me soon enough as it is insisting that it needs to be translated! 🤪

[3djc]

I have choosen those terms to allow easier searching for solution, since occurence should be quite rare (also why I haven't made it translatable). Edgetx wrong firmware probably leads to too much answers, edgetx wrong mcu far far less.

Exactly. And if we have a FAQ entry for that up pretty much straight away... there is a good chance it will come up as pretty much the first result if anyone searches for it...
