AM3358: U-boot-spl not booting

ravi rk

Part Number: AM3358

Hi,

I am working on the am3358 custom board,I can see CCCCCC printed on uart0.

I try to load u-boot-spl through JTAG, but I didn't saw any console print. For EEROM I made following changed in board.h

static inline int board_is_evm_sk(void)
{
//return board_ti_is("A335X_SK");
return 1;
}

and in board_detech.c

static int __maybe_unused ti_i2c_eeprom_init(int i2c_bus, int dev_addr)
{
int rc;

/*if (i2c_bus >= 0) {
rc = i2c_set_bus_num(i2c_bus);
if (rc)
return rc;
}

return i2c_probe(dev_addr);*/
return 0;
}

And I debug through JTAG,u-boot-spl was reach upto enable_caches(); after that goto this line b 1b /* hang and never return */ in vectors.S and somtimes its get hang afte enter into void board_init_r(gd_t *dummy1, ulong dummy2)

SDK Version : ti-processor-sdk-linux-am335x-evm-06.00.00.07

Kindly help us to resolve this issue

Hello Ravi,

Could you please share how you are loading the code through JTAG? Also, please share the process used to configure the DDR on your custom board.

Hi Krunal,

I followed this link "http://processors.wiki.ti.com/index.php/Sitara_Linux_Training:_uboot_linux_debug_with_ccsv5" to load u-boot-spl.bin through JTAG.

And I didn't configure DDR because I try to loading MLO. I hope MLO doesn't need a DDR configuration to boot.

Regards,

Ravi

Hello Ravi,

MLO will configure the DDR and copy u-boot.img to DDR. Please make sure the DDR is initialized before loading Uboot images. Also, please refer to the following thread for debugging SPL.

Thanks, Krunal

I will do the DDR configuration in code, but before that, I just want to know any message will print in the console before DDR initialization.

And let me know is my changes for EEPROM is correct or wrong.

Regards,

Ravi

Hi Ravi,

The changes look correct and I am wondering if you have any updates.
