Error CRC bootloader
Hello, I use libretiny and ltchiptools in my firmware. some devices flash normally, but now I'm faced with such a problem. This is a relay on a BK7231N chip
P.S. I have already figured out the pins, I tried openbeken, it is flashing normally
Do you have a stock firmware dump of the device? You have most likely corrupted the bootloader somehow, so it can't boot again. It is also possible that your device came with different bootloader keys and doesn't boot because of that. In either case, having a stock firmware dump is necessary.

I saved the stock firmware, I'll try to restore it. Is the firmware address stored in the ufl file during the build? Can I see it, maybe it's stitching the wrong way?
No, there isn't anything like "firmware address". Try restoring the entire firmware dump (it should be 2 MiB in size). In ltchiptool, open the file for writing, disable "auto-detect parameters" and clear the start/skip/length fields. Then flash the file. The device should be fully functional with its stock features.
Is it a Tuya Smart device, or a different brand? (like SBER, eWeLink, etc.)
