TMS320F2812 is designed to boot from external boot space. Initially the bootloader is loaded to FPGA Dual port ram by ARM processor. The boot vector is perfectly fetched from FPGA using CS6&7 and it jumps to the bootloader location (using CS2) in FPGA dual port ram and starts file fetch. Our observation is once the boot-loader is fetched and during its execution the CS2 stops transition and stay high. This issue occurs randomly in some PCBAs only. Is there any known issues and solutions similar to this?
