Hardware Tools¶
SPI flasher¶
For chips that don¡¯t have bootrom and no bootloader in flash, you need to use SPI to download firmware. After bootloader has been downloaded into flash, you can use UART to downloadfirmware later. For chips that have bootrom(BK7231N, etc), you can use SPI or UART to download firmware.
UART TTL¶
Make sure chip supports bootrom or its flash has bootloader. We recommend CH340 UART to download firmware.

Download via UART¶
Make sure chip supports bootrom or its flash has bootloader. We recommend CH340 UART to download firmware.
After click Burn, power off and on the device to let the device enter bootrom or bootloader.
Note
For chip BK7231N, choose the burn target be BK7231N, BK7231 for other chips.
For chip BK7231N, start address is 0x0, other chips are 0x11000.
