Tool/software: Linux
Hi,
We are working on our first custom board with AM3352. It is based on Beagle Bone Black and added some other peripherals. I hard code EERPOM values, rebuild U-boot and download u-boot successfully to the board from UART. But the board hangs after "Starting Kernel...". SD on the board is not working. All code is running in SDRAM. I use the latest SDK 4.0.0.04 from TI website. I changed device tree several time but no luck. Later I delete everything in the device tree but only keep UART0, Ethernet 0 and I2C0. It is still the same.
