bjoernq / blash

A tool to flash BL602 via JTAG + serial without pressing buttons / setting jumpers

Hi there ✨

I'm excited about everything Rust and especially embedded stuff.

blash's Issues

Download eflasher using OpenOCD?

Hi!

I find this project really interesting, and I would like to reproduce the same functionality in an OpenOCD script, that would integrate more easily in my dev environment. I only need the part that downloads the eflasher bin into the RAM.

I hope you don't mind if I ask some help, even if it's not directly related to this project?

I tried to read the code (but I don't know Rust, unfortunately), and here's what I've tried so far:

halt
reset

mwb 0x22010000 0x73
mwb 0x22010001 0x13
mwb 0x22010002 0x0
mwb 0x22010003 0x30

reg t1 0x80000000
reg pc 0x22010000
step

load_image /home/jf/git/blash/bin/eflasher.bin 0x22010000 bin

reset

reg pc 0x22010000

resume

/home/jf/git/blash/bin/eflasher.bin is the file eflash_loader_40m.bin with the first 192 bytes stripped.

OpenOCD runs this script without error, but it doesn't seem to work, and the MCU does not run the bootloader code (I checked the serial output).

Is my understanding of the code from Blash correct? Did I miss anything?

Thanks!

Add support for Pine64 JTAG adapter?

Hi!

I'm currently experimenting on the Pine64 BL602 board from Pine64. I tried Blash using my Sipeed JTAG adapter and it works perfectly, thanks a lot for creating this tool!

Now, I was wondering what would it take to add support for the Pine64 JTAG adapter? It should be pretty similar to the Sipeed one, but have a different PID/VID :

• Sipeed : Bus 001 Device 029: ID 0403:6010 Future Technology Devices International, Ltd FT2232C/D/H Dual UART/FIFO IC
• Pine64 : Bus 001 Device 030: ID 0403:6014 Future Technology Devices International, Ltd FT232H Single HS USB-UART/FIFO IC

Any idea if that would be possible? I would be happy to help but I don't know Rust, and I don't know where to start :/

Here the output of blash when I tried using the Pine64 adapter:
