I am having a board with eight TS201 processors configured for 500 MHz clock booting via EPROM, after power on some of the processors boots from EPROM and able to excute the user instructions(blinking LED's) and the remaining processors are not working. The processor which are working onetime is not working at othertime. When debugged by modfying the boot kernel, we came to know the boot kernel code is not executed. It is not responding to emulator connectivity. I dont know what the processor is doing after power on. Can somebody suggest me, what could be reason for this behaviour or how to debug this issue.
