WAIT! NONONONONO! DON'T DO THIS!
WRITING THERE OVERWRITES THE FIRMWARE!
...Maybe. My watch still boots.
It's been a while, but I thought 7000c000
was the address of PSRAM or something along those lines. Perhaps your device hasn't initialized it yet.
I hope the device hasn't been bricked. Please do keep us updated.
Turns out I was accidentally using the wrong branch oops! Watch wasn't bricked, so that's nice!
Alright, I think I'll close my mistake.
Well, at the very least it's wrong for my two specimens.
"FERNLY_USB_LOADER_ADDR" should be defined as $1000a5b0, not $7000c000. How do I know this?
Well, I spent the entirety of last night messing with these two smart watches. What I SHOULD have been doing was inspecting the inside of my eyelids but whatever...
Anyway, I had my CH431a hooked up to one of them, so I got to capture the serial output from the bootloader.
I read your reply to another issue regarding the MT6261 and addresses. Sure enough, the boot process progresses somewhat farther!
Still hangs though, but I think I can fix that.
