Is the below recipe the way to put the environment in flash?
Obviously not - as it doesn't work.
I can't seem to find any other instructions on this...
There are lots of working board config files.
I'm using a PPChameleonEVB, and am trying to move the u-boot environment into flash. I've modified the include/configs/PPChameleon.h file as follows:
This statement is bogus. In the default configuration of the PPChameleonEVB board, the envrionment _is_ already in flash, and no changes are needed at all.
#define CFG_ENV_IS_IN_FLASH 1
OK.
#define CFG_ENV_ADDR 0xFFFFA000 #define CFG_ENV_OFFSET (CFG_ENV_ADDR - 0xFFFC0000)
This is redundand and extremely bad style. Why don't you use CFG_FLASH_BASE instead of the hardwired "magic" constant?
#define CFG_ENV_SIZE 0x2000
I really don't understand why you don't just look at the existing source code and use this. It reads ("include/configs/PPChameleonEVB.h"):
381 #define CFG_ENV_IS_IN_FLASH 1 /* use FLASH for environment vars */ 382 #define CFG_ENV_ADDR 0xFFFF8000 /* environment starts at the first small sector */ 383 #define CFG_ENV_SECT_SIZE 0x2000 /* 8196 bytes may be used for env vars*/ 384 #define CFG_ENV_ADDR_REDUND 0xFFFFA000 385 #define CFG_ENV_SIZE_REDUND 0x2000
