AM3358: SPL boot problem

Part Number: AM3358
Other Parts Discussed in Thread: TPS65217

I made a new custom board using am3358.

But my device can't boot in spl step

pmic : TPS65217

eeprom : not used (to pass EEPROM check, i modified board/ti/common/board_detect.c file to hard coding)

memory : MT41K256M16TW-107 AAT (I tuned it with reference http://processors.wiki.ti.com/index.php/Sitara_Linux_Training:_Tuning_the_DDR3_Timings_on_BeagleBoneBlack )

This is my log :

Fisrt, I transfered a 'u-boot-spl.bin'.

But 'C' character was broken like above log. so I could not upload u-boot.img file after this step.

Please let me know what to check.

    After sending the u-boot-spl.bin you should immediately send the u-boot.img, without waiting for "C" characters. They will not appear after u-boot-spl.bin has been sent. See software-dl.ti.com/.../Foundational_Components_U-Boot.html

    Hello Hanjun,

    Please, see this thread. You need to use the u-boot-spl.bin and u-boot.img from the latest Processor SDK.

    Best regards,
    Kemal
