Part Number: PROCESSOR-SDK-AM335X
Other Parts Discussed in Thread: TPS650250
Tool/software: Linux
Hi all,
I have a custom board design base on AM335x Starter Kit board, my custom board have some difference with AM335x Starter Kit like:
- SDRAM: 128 MB (use MT41J64M16)
- RTC use S35390A
- Ethernet use KSZ9021RN
- PMIC use TPS650250
I'm using ti-processor-sdk-linux-am335x-evm-04.00.00.04, i can custom u-boot and boot (MLO, U-boot) from SD-Card.
But when i try custom device tree and boot dtb file and zImage file, the board is hang at "Starting kernel ...", and reload.
The Terminal show:
