Hello,
i'm not sure if this is the right place for this question...however, here it is:
i'm using a BDI3000 to program uboot to the flash (Spansion S29GL512P) on a MPC5200B base board. Erasing / Programming works fine as long as the flash sectors are not protected (via PPB bit). On a protected sector the erase command fails (what makes sense). I thought I can use the unlock command to unprotect the sectors, but this command seems not to work:
unlock 0xfff00000 1000
Unlocking flash at 0xfff00000 # Invalid parameter for flash programming
Any ideas what I'm doing wrong?
Flash configuration: [FLASH] CHIPTYPE MIRRORX16 CHIPSIZE 0x04000000 BUSWIDTH 16 WORKSPACE 0x00000000
