Tool/software: Linux
Hi,
My development environment is as follows.
PC os: Ubuntu 18.04(Virtual machine), SDK : TI-linux-am437x-evm-05.00.00.15, IDE : ccs v8, debugger : XDS110
& have a AM437x starter kit board.
1. An error occurs when U-BOOT is loaded after memory loading SPL from CCS on the board.
reference this link : http://processors.wiki.ti.com/index.php/Sitara_Linux_Training:_uboot_linux_debug_with_ccsv5#Key_Points_5
[Perform SPL Debug] is fine, but next step [Perform U-Boot Debug] occur <stageboot_error>.
It`s SPL start address : 0x402F4000, U-boot start address : 0x80800000?
2. I want to verify the debug of u-boot / spl with UART0.
so, added CONFIG_DEBUG_UART_OMAP into ".config" to use debug_uart_init().
build fine but can`t find messages.
3. In SPL/UBOOT, how to configure it to use Single RAM( DDR3 16bit width ).
Can we just refer to [Technical Reference Manual] EMIF part and change emif_regs.sdram_config?
or Do something at 'arch/arm/mach-omap2/am33xx/emif4.c : config_ddr()' < 'board/ti/am43xx/board.c : sdram_init()'
Thank you reply
Regards,
Hosung HAN.
