Other Parts Discussed in Thread: OMAPL138, OMAP-L138

Hi,

I've built UBL, UBOOT for my customized board inspired from OMAPL138_LCDK card.

I did so modifications:

- on parameters of my DDR2 (MT47H32M16) :

status |= DEVICE_ExternalMemInit(0x000000C5, 0x00134A22, 0x2C927209, 0x7013F924, 0x000002EE, 0x00000000);

- changed communication from UART2 to UART1 on uboot.

->omapl138_lcdk.h :

- CONFIG_SYS_NS16555_COM2 DAVINCI_UART1_BASE

- CONFIG_SYS_NS16555_CLK clk_get(1)

- CONFIG_CONS_INDEX 2

->omapl138_lcdk.c : into lpsc[] structure, I changed DAVINCI_LPSC_UART2 to DAVINCI_LPSC_UART1

But when I boot my card, system stops to "Jumping to entry point at 0xC1080000"

Here my console:

---------------------------------------------------------------------------

OMAP-L138 LCDK initialization passed!
Booting TI User Boot Loader
        UBL Version: 1.65
        UBL Flashtype: NAND
Starting NAND Copy...
Valid magicnum, 0x55424CBB, found in block 0x00000006.
   DONE
Jumping to entry point at 0xC1080000.

---------------------------------------------------------------------------

please, could you help me? thalks

Hi,

Please don't create multiple post for the same issue.

1) include/asm/arch/hardware.h

#define DAVINCI_SYSCFG_SUSPSRC_UART0       (1 << 18)
#define DAVINCI_SYSCFG_SUSPSRC_UART2       (1 << 20)
#define DAVINCI_SYSCFG_SUSPSRC_UART1       (1 << 19) //Titus

2) include/configs/omapl138_lcdk.h

/*
* Serial Driver info
*/
#define CONFIG_SYS_NS16550
#define CONFIG_SYS_NS16550_SERIAL
#define CONFIG_SYS_NS16550_REG_SIZE   -4   /* NS16550 register size */
#define CONFIG_SYS_NS16550_COM2   DAVINCI_UART1_BASE /* Titus : Base address of UART1 */
#define CONFIG_SYS_NS16550_CLK   clk_get(DAVINCI_UART2_CLKID)
#define CONFIG_CONS_INDEX   2       /* Titus : use UART1 for console */
#define CONFIG_BAUDRATE       115200       /* Default baud rate */
#define CONFIG_SYS_BAUDRATE_TABLE   { 9600, 19200, 38400, 57600, 115200 }

3) board/davinci/da8xxevm/omapl138_lcdk.c

    /* setup the SUSPSRC for ARM to control emulation suspend */
   writel(readl(&davinci_syscfg_regs->suspsrc) &
           ~(DAVINCI_SYSCFG_SUSPSRC_EMAC | DAVINCI_SYSCFG_SUSPSRC_I2C |
       DAVINCI_SYSCFG_SUSPSRC_SPI1 | DAVINCI_SYSCFG_SUSPSRC_TIMER0 |
       DAVINCI_SYSCFG_SUSPSRC_UART1),//Titus
           &davinci_syscfg_regs->suspsrc);
ii)

    /* enable the console UART */
   writel((DAVINCI_UART_PWREMU_MGMT_FREE | DAVINCI_UART_PWREMU_MGMT_URRST |
       DAVINCI_UART_PWREMU_MGMT_UTRST),
           &davinci_uart1_ctrl_regs->pwremu_mgmt);

iii)

static const struct lpsc_resource lpsc[] = {
   { DAVINCI_LPSC_AEMIF },   /* NAND, NOR */
   { DAVINCI_LPSC_SPI1 },   /* Serial Flash */
   { DAVINCI_LPSC_EMAC },   /* image download */
   { DAVINCI_LPSC_UART1 },   /* Titus : console is changed to UART1 from UART2 */
   { DAVINCI_LPSC_GPIO },
#ifdef CONFIG_DAVINCI_MMC
   { DAVINCI_LPSC_MMC_SD },
#endif

Apply the above changes in u-boot source code and please let us know results.
