why does every new travel camera firmware update force a full stm32f7 bootloader reflashing

ngl i've been trying to chase that perfect sunrise at machu picchu and guess what? the latest a7iv firmware just dumped a massive stm32f7 update that wipes my custom intervalometer settings rn

the hype about "smart auto‑focus" is just an excuse for manufacturers to ship bloated i2c drivers that break my esp32‑c3 trigger board

here's the broken loop i keep hitting:

• push new firmware via sd card
• device re‑enumerates as mass storage
• bootloader resets to stock wiping custom dma buffers
• i spend hours reflashing the stm32f7 with open‑ocd just to get my 10‑second timelapse back

and the community forums keep saying "just wait for the next patch" like we have time when the sun's already set

i'm exhausted the only thing i trust now is a good old analog timer lol

anyone else stuck in this endless cycle of firmware hype vs real world shooting any hacks that actually survive a vendor's "improved" release would be appreciated
