Hi All, Will appreciate if someone can guide me how to debug this inside SEC (security co-processor) core.
The linux driver is writing descriptor into the FETCH-Register(0x2048) for Random Number generation execution unit(RNG-EU). The request came through a test program from user space. The RNG generation request never seems to complete as my ISR is not invoked. I checked the CCPSR(Crypto Channel Pointer Status register = 0x2010) and it has value=0:7(0-31 : 32-63 bits). 7 means "channel_error". But its always there even before I write the RNG descriptor to Fetch-register. 1. I can read the ID register and verified it is 0x09000000. 2. I can see my ISR is registered(0x47) under /proc/interrupts. I don't see anything wrong with the descriptor which is very simple Random Number Generation request. regards -vikas aggarwal
