Hi everyone, As mentioned in SMDK6410_IROM_APPLICATION_NOTE_REV_1.00, the recommended partitions for SD/MMC card are as following: -->First Block------------------------------------------------<--Last Block ---User File System---Kernel---BL2---BL1(8K)---Signature(512Byte)---Reserve But after fused 1G card by using SD-Flasher tool, I saw that: in my case u-boot.bin took 208K of memory, and SD-Flasher tool will fill last 416 block (416 = 208 x 2) by u-boot.bin without partition as recommended. As I saw, the first byte of u-boot.bin took the first byte of 416 block from the last block. And it got the end at the last byte of last block. Further, u-boot still run normally. So, who can let me know, what was wrong here? Are there any confusion in Application Note. - DangVV
