I am using a custom board consisting of ADSP-TS201S and it has been running successfully as far as the preliminary tests are concerned since the last 20 days. 3-4 days before I tried to program my on-board FLASH - JS28F128J3 for booting. I dont know if it was successful.
Today, though when I am trying to reconnect my board, I get "Determining Scan Path Length" test failed. I read somewhere that inappropriate contents of FLASH can cause JTAG chain to fail. Could this be the reason since, it was the last thing I tried for testing.
Any other suggestions would be highly helpful.
Thanks and Regards,
