Subject: [U-Boot-Users] Question about CFG_ENV_ADDR during RAMBOOT
Date: Wed, 16 May 2007 14:58:05 -0500 [thread overview]
Message-ID: <464B624D.2050102@freescale.com> (raw)
On a lot of boards, if CFG_RAMBOOT is defined, the following code is compiled:
#define CFG_ENV_ADDR (CFG_MONITOR_BASE - 0x1000)
#define CFG_ENV_SIZE 0x2000
This means that the environment is stored 0x1000 bytes before the start of u-boot.bin.
Doesn't that mean that if the environment is larger than 0x1000 bytes, that it will
overwrite the beginning of u-boot.bin whenever someone does a saveenv?
