So, yesterday I bough a NOS MIPS32 YK board, it's a kind of cheap Atlas clone, without gadgets (HEX LCD, ps/2, VGA, fpga-timers ... ) but comes with a EJTAG connector.
Basically it's
- CPU (1 CPU, 1 core @ { 12.5, 25, 50, 100 } Mhz)
- programmable clock-PLL { 1x, 2x, 4x, 8x } clock
- soldered dram (16Mbyte)
- soldered flash (512Kbyte)
- Ethernet chip (CS8900)
- USB (NEC EHCI)
- EJTAG
I don't want to use my super-professional EJTAG ICE, because the tiny board is for hobby purpose, while the ICE?pro is ... for when I have to assist my clients (and I have already applied the sticker the sticker "pro" on the ICE plastics to appear more "pro"-fessional ;D ) ...
so, I am looking for a cheap debugger and found the, Bus Blaster-V3c for MIPS (https://www.seeedstudio.com/Bus-Blaster-V3c-for-MIPS-Kit-p-2258.html) kit.
It's supported by several software, including OpenOCD: good!
SeeedStudio reports it as out of stock, but still available on Aliexpress (40..50 Euro), as well as the v4 (40..50 Euro): and here my doubt ... should I buy the v3c or the v4? Same connector, both EJTAG, and the price is similar.
umm the v4 seems to have a physically bigger CPLD with more I/O exported to the PCB, and probably more LE resources, even if it's used as "voltage-level" buffer.
Mumble :-//
