[songsongman]

here is the log : DDR version 1.06 20170424 In DDR3 786MHz Bus Width=32 Col=10 Bank=8 Row=15/15 CS=2 Die Bus-Width=16 Size=2048MB ddrconfig:6 OUT Boot1 Release Time: 2017-05-18, version: 2.43 ChipType = 0x11, 124 SdmmcInit=2 0 BootCapSize=2000 UserCapSize=7456MB FwPartOffset=2000 , 2000 SdmmcInit=0 2 StorageInit ok = 20774 Raw SecureMode = 0 SecureInit read PBA: 0x4 SecureInit read PBA: 0x404 SecureInit read PBA: 0x804 SecureInit read PBA: 0xc04 SecureInit read PBA: 0x1004 SecureInit ret = 0, SecureMode = 0 LoadTrustBL No find bl30.bin No find bl32.bin Load uboot, ReadLba = 2000 Load OK, addr=0x200000, size=0xa7fac RunBL31 0x10000 NOTICE: BL31: v1.3(debug):f947c7e NOTICE: BL31: Built : 09:28:45, May 31 2017 NOTICE: BL31:Rockchip release version: v1.3 INFO: ARM GICv2 driver initialized INFO: Using opteed sec cpu_context!

• I tracing the code , then I find code will not continue when execute as below:
• u-boot\arch\arm\mach-rockchip\rk3328\rk3328.c
• int dram_init_banksize(void)
• {
• size_t max_size = min((unsigned long)gd->ram_size, gd->ram_top);
• /* Reserve 0x200000 for ATF bl31 */
• printf("00000000000000 \n");
• gd->bd->bi_dram[0].start = 0x200000;
• printf("11111111111111 \n");
• gd->bd->bi_dram[0].size = max_size - gd->bd->bi_dram[0].start;
• return 0;
• }
• As we can see, it will printf 0000000000000000, but not print 1111111111111111.
• So it stoped in "gd->bd->bi_dram[0].start = 0x200000;" .
• ( PS: Our PCBA can run android uboot and DDR4 ubuntu uboot.)
• Could you please give me some advice , please.

We never meet similar issue, did you change any boot code? pls try to print the address of gd->bd->bi_dram[0].start.
