Hi,
I have a custom board with an old LH75401 processor and 2Mb of external Flash.
When I try to connect to it soetimes connects but most of the time it does not. When it does it connects really slow. Even when i set j-flash to automatic speed. I can read the CFI info. But when I try to read the flash it errors with:
PC of target system has unexpected value after checking target RAM. I tried different JTAG speeds From low to high but nothing seems to work correctly.
Other programs (like J-Mem) seem to work correctly and when measuring all signals they seem correct.
It works correctly with a different board (STM32 controller).
