I am trying to debug a tutorial program provided by Actel on its SmartFusion Development Kit using Keil MDK ARM 4.70a. As per the tutorial, I have ensured all the jumper settings are in order. Initially, when I tried to debug the program, I got a message displaying "Need to update the firmware", to which I clicked "Ok". After a while though, I got error message stating that "Firmware update failed". After this message, whenever I try to debug, I get an error message stating "No JTAG Devices found". I have checked the jumper settings again and again, but to no avail. Please help me out. Thanks!
And yes, I am using a Keil ULink2 Debugger.
