Hi,
Does anyone have good idea for my customer?
My customer is designing AM3874 system. The customer would like to monitor the internal failure of AM3874.
For example,
In case of the external memory, external logic(ASIC etc) can watchdog the CS signal. However, if the external access never happened, it is impossible to diagnose what is happened in CPU.
I know Hercules has many diagnositc function. But AM3874 doesn't have same function.
Some peripheral lke as USB memory, ethernet , graphic, and so on are same situation. When something error happen in internal CPU, It is very useful that the status is output from some GPIO pin. Is it possible to make the similar function?
If you have any idea, please let me know.
Best regards, Michi
