JTAG support (See below for BL602 impact)
- BL602 multiplexes four GPIO pins to provide the familiar JTAG lines:

GPIO17 - TDI GPIO11 - TDO GPIO12 - TMS GPIO14 - TCK The chip boots with these lines in JTAG mode.

- Note: Current schematic, cc1 and cc2 share one 5.1KOhm resistor. Next schematic design will separate out the cc1 and cc2 has it own 5.1KOhm resistors
The board uses a CH340 Serial/USB adapter. This chip is commonly used in Arduino-class development boards. It is a full speed (12Mbps) USB interface and has vendor ID 0x1a86 with product ID 0x7523.
The GPIO pins (11, 12, 14, 17) plus the nearby RESET, POWER, and GND pins are all located on one side of the board, on J1.

Planned to be available in at least three form factors:

There are currently a number of loaders in progress, each with differing degrees of completeness and success on various operating systems.

In the build tree, there is BLFlashCube for Windows and a flash_build for Linux, neither with source.
bl60x-flash is in Python and has been reported successful on MacOS catalina (10.15.6) by Punnerud and madushan1000.
BLOpenFlasher is a WIP, written in go, by Bouffalo Labs to provide source for a flash utility.
[1] is a Python utility in development.
