Hi all ,

Am using a BF537 Stamp board with the last mature u-boot on it.

When i launch the commands :

bfin>protect off all

bfin>erase 0x20030000 0x203FFFFF

to erase the part the am reserving for the kernel image and the rootfs ,uboot says

bfin>Erased 61 sectors ; so i assume that the erasing operation went ok

but If after that i try to write a file -the rootfs.jffs2 - which size is 2950632 (2d05e8 hex) ,

the boards start copying then after some seconds it says :

bfin> cp.b 0x1000000 0x20030000 $(filesize)

Copy to Flash... Flash not Erased

can any one tell me what could be my error knowing these further infos :

1.when erasing the flash for every sector erased the uboot screens a dot (.) ,in my case it screens about 23 dots -for the first 23 sectos it erased- whith a period of 1second between each 2 of them- and then it screens all the rest of the 61dots all at once.

2.when i try to copy a file of 900k -the vmImage- starting from the address 0x20030000 everything is fine

3.when i try to erase from any address greater then 0x201f0000 ,the bootloader says without any delay that the sectors where erased properly

4.I noticed that everytime i issue an erase command the uboot is really erasing the sectors till sector 0x2020000 ,then it just says the operation went ok without any delay ;so for example when i say :

bfin> erase 0x201E0000 0x203FFFFF

i get one dot ,the another one after 1 sec then i got all the rest at once with the message :

................................ done

Erased 32 sectors

5.I tried to erase further sectors then the 0x20200000 0x202FFFFF one ,but i get the samething

Regards

Oussema
