Is there a way to know the U-Boot partition size the at91loader expects?
Till now, there is no such function. However, if you use new bootstrap, it will show useful information as following:
---8>--- AT91Bootstrap 3.5.3 (Thu Apr 25 10:08:24 CST 2013)
NAND: ONFI not supported NAND: Manufacturer ID: 0xec Chip ID: 0xda NAND: Disable On-Die ECC NAND: Press the recovery button (BP4) to recovery NAND: Using Software ECC NAND: Image: Copy 0x80000 bytes from 0x40000 to 0x21f00000 NAND: Done to load image ---<8---
I really want to get a UBIFS root file system on this board. But, I haven't figured out how to do that yet, nor have I found a rootfs small enough to fit yet.
For UBI file system support 1. if you want to mount, read or something else with u-boot, please reference to <include/configs/at91sam9x5ek.h>. Some quote information ---8>--- #define CONFIG_MTD_DEVICE #define CONFIG_CMD_MTDPARTS #define CONFIG_MTD_PARTITIONS #define CONFIG_RBTREE #define CONFIG_LZO #define CONFIG_CMD_UBI #define CONFIG_CMD_UBIFS
#define CONFIG_SYS_MALLOC_LEN (4 * 1024 * 1024) // for mount ubifs ---<8---
2. if you just want use ubifs as rootfs. just one thing for u-boot, it is bootcmd, please also reference <include/configs/at91sam9x5ek.h>.
