Hello,

 

I am building my custom imx28 based board with nand flash without battery. My board has not sd card input so i am planning to write a kernel and filesystem to nand with uboot.

 

I edited imx-bootlets-src-10.12.01 for no battery (uncomment //#define NO_DCDC_BATT_SOURCE in /power_prep/power_prep.c)

 

I found some other u-boot named like uboot-imx, u-boot, u-boot-fslc (i tried all) and built with imx28evk_nand_defconfig config.

 

log is here after load sb file.

U-Boot 2015.10-00059-g8ee67c1 (Jul 16 2016 - 15:05:09 +0300)

 

CPU:   Freescale i.MX28 rev1.2 at 454 MHz

BOOT:  ğŸåğŸåğŸåğŸåğŸåğŸå

SPI:   ready

DRAM:

 

It stucks before displaying dram size as if it were in a while loop and boot mode displays unknown characters.

How can i fix this error?
