u-boot for Nios-II now includes support for the EPCS controller core. Try 'help epcs'.
Support includes:
- Device identification
- Read to memory
- Write from memory
- Verify from memory
- Protection control
u-boot for Nios-II now supports the following filesystems:
- JFFS2
- CRAMFS
- FAT (12/16/32)
Access to the Altera devkit CompactFlash in TrueIDE mode is also supported.
However, unlike Nios-32, the Nios-II examples do not have CompactFlash
support in the system module -- so you'll have to add it in yourself.
You'll also have to configure and rebuild the u-boot sources to enable
IDE/FAT support (IDE/FAT is not included in the new pre-built binary):
In include/configs/PK1C20.h add the following to the CONFIG_COMMANDS
macro: CFG_CMD_FAT and CFG_CMD_IDE.
JFFS/CRAMFS is included in the pre-built binary. Two partitions are defined:
0 : 0x0020_0000 (2MB) -- for linux kernel
1 : 0x0080_0000 (1MB) -- sram for testing JFFS/CRAMFS images
Use the chpart command to select the active partition. u-boot will automatically
detect cramfs/jffs2.
If you have problems or questions, please let me know. Enjoy.
