I have two boards which are not detecting in USB serial download mode to flash U-boot and Kernal image.
All power to the processor is working fine. Reset sequence is proper and Reset logic state is High after power up.
The Boot mode selection pin settings are proper with proper logic level.
Is there any way to debug using JTAG interface? We have JTAG interface on our board. If yes, can you suggest the connection and required JTAG debugger tool?
Any other suggestions would be greatly appreciated.
