ah wicked, thanks for checking it out and fixing it, looks like i was pretty close. I have to double check the 446VET config part to make sure its the same as 446ZET same as octopus, but there seems to be little work done on mbed with the 446ZE and even less work done with the 446VET, they dont even have a target config for it in the github, only on mbedos website listed under b96b_446. Ill make a config and test it out after dinner.

I have been over the clock file you made, and the clock file in the other firmwares/the 407 clock file with a fine tooth comb, and just about everything seems the same and in the right place and compiles fine it just doesnt kick into gear. Ive been looking for the offical mbed 446ZET boards, but they are backordered and not expected to be in stock until sept 2022....

Hmm, this is always the challenge with new board. Did the firmware flash? The Monster8 uses a 64kB bootloader offset. 0xC000 vs 0x8000 like the SKR boards.

Anything on the uart at all? If nothing then the firmware hasn't booted. If rubbish then a buad rate / system clock setup issue.

One step closer. Did you have a config.txt on the SD card? Does is "fail" and show a crazy JSON length?

If is just hangs at no filesystem then it's trying to mount a poorly formatted SD card.

hmm yeah it says
No File system found...opening "/fs/config.txt"... Fail :(
json config length -167

Yeah, I def had the config loaded this time

Its the same SD card I use for all my remora boards
i figured fs meant filesystem, or do i need to make an /fs/ directory?
