Don't know it you care at all :-), but in my default PPChameleon config
this definition is hidden by the surrounding
#define ENVIRONMENT_IN_EEPROM
#ifdef ENVIRONMENT_IN_EEPROM

#define CFG_ENV_IS_IN_EEPROM	1

Good idea. I removed "CFG_CMD_EEPROM" from the "CONFIG_COMMANDS" - that
should do it...
Thanks again!
