Flashing

Flashing software

• BKwriter v1.60
• hid_download_py

⚠️Warning

BKwriter 1.60 has proven unreliable for flashing the BK7231N chips. When in 'BK7231 mode', it fails with "invalid CRC"; in 'BK7231N mode' it fails to unprotect the device.

For BK7231N, use the Python script.

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.
