Hi there,
I have a question about erasing flash sectors, please tell me what steps I did wrong, thank you.
The following is my boad using u-boot command "flinfo": Bank # 1: SGS Thomson PSD4256G (1 M, uniform sector) Size: 1 MB in 16 Sectors Sector Start Addresses: 20000000 (RO) 20010000 (RO) 20020000 20030000 20040000 20050000 20060000 20070000 20080000 20090000 200A0000 E 200B0000 E 200C0000 E 200D0000 E 200E0000 E 200F0000 (RO)
If I want to erase sector from 20020000 to 20090000 for example, I use the command "erase 20020000 2009ffff" to erase flash, it seems to be ok from erase message:
Erase Flash from 0x20020000 to 0x2009ffff .............. done Erased 8 sectors
But when I use "flinfo" command to see whether those sectors are erased or not, it shows the same above message: Bank # 1: SGS Thomson PSD4256G (1 M, uniform sector) Size: 1 MB in 16 Sectors Sector Start Addresses: 20000000 (RO) 20010000 (RO) 20020000 20030000 20040000 20050000 20060000 20070000 20080000 20090000 200A0000 E 200B0000 E 200C0000 E 200D0000 E 200E0000 E 200F0000 (RO)
If I understand correct, sectors from 20020000 to 20090000 should be displayed (E), but those aren't. I don't know what step I did wrong.
Regards, Joe.
