PineCone BL602 EVB information and schematics
- Approximate dimensions: 26mm x 43mm
- Board layout:
- PineCone BL602 EVB schematic ver 1.1
- 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.
Datasheets for components and peripherals
- Bouffalo BL-602 SoC information:
- Bouffalo Lab BL602 SoC Datasheet V1.2
- Bouffalo Lab BL602 SoC Datasheet V1.1
- Bouffalo Lab BL602 SoC Reference Manual V1.1
- Please note that the Chinese wording "寄存器描述" means "Register Description" in reference manual ver 1.1
- USB/Serial adapter:
Misc notes
Planned to be available in at least three form factors:
- NUT-01S -> ESP-01S
- NUT-12S -> ESP-12S
- NUT-15 -> RTL8723/AMPAK
Loading code
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.
Development efforts
- PineCone BL602 GitHub Page (PINE64 fork) has compilers, linkers, and all the code to build on Windows, Linux(x64), and MacOS.
- Bouffalo Lab GitHub Page
- BL602 Developer organize documentation GitHub Page
- BL602 reverse engineering working group
- Linux kernel module
