Thanks for the report! Interesting to see a new label in the wild (BYK903).

@neduard I just recently realised that
620f0b67a91f7f74151bc5be745b7110is just all zeros in the bootloader section. Do you happen to have a payload for your keyboard that you can share with me? I believe the actual flash size for this device is smaller than 64kB.neduard commentedon Sep 9, 2026
Hey @carlossless
nice, yeah exactly - that's what I was mentioning in my previous comment but it's a good shout about the device size
I do indeed: https://gist.github.com/neduard/98858d988339070cf7f5ea24902f69ce
It does seem to stop at address
0x7b46which would indicate it's 32kb (with bootloader starting at 0x7000 ?) . I tried passing firmware and bootloader size but didn't get a known md5:carlossless commentedon Sep 9, 2026
Thanks! Updating sinowisp here: #160
