flashing BK7231N

Building for BK7231N

Same as for BK7231T, but use BK7231N SDK and you also might need to rename project directory from OpenBK7231T_App to OpenBK7231N_App: https://github.com/openshwprojects/OpenBK7231N

Flashing for BK7231N

BKwriter 1.60 doesn't work for BK7231N for me, in BK7231 mode it errors with "invalid CRC" and in BK7231N mode it fails to unprotect the device. For BK7231N, one should use:

https://github.com/OpenBekenIOT/hid_download_py

Flash BK7231N QIO binary, like that:

python uartprogram W:\GIT\OpenBK7231N\apps\OpenBK7231N_App\output\1.0.0\OpenBK7231N_app_QIO_1.0.0.bin --unprotect -d com10 -w --startaddr 0x0

Remember - QIO binary with --unprotect and --startaddr 0x0, this is for N chip, not for T.
