Hello
I have a platform modify from powerpc 405EP(Taihu evb). I try to port u-boot from Taihu evb by using "taihu_config".
There are 4M+4M flash on the board, but I found that I can not erase flash from ff800000--ff803fff.I had try "protect off all" and "erase all", but still don't work.
just like this : => era ff800000 ff803fff
.. done Erased 2 sectors => md ff800000 ff800000: 27051956 682e4eec 4c070a61 00168502 '..Vh.N.L..a.... ff800010: 00000000 00000000 ad640a83 05070201 .........d...... ff800020: 4c696e75 782d322e 362e3332 2e330000 Linux-2.6.32.3.. ff800030: 00000000 00000000 00000000 00000000 ................ ff800040: 1f8b0808 600a074c 0203766d 6c696e75 ....`..L..vmlinu ff800050: 782e6269 6e2e3136 39363100 e45b0f70 x.bin.16961..[.p ff800060: 14559aff 7a7a0213 08cb0881 0d24988e .U..zz.......$..
"erase" command works every where on flash besides "ff800000--ff803fff" Thus I can still erase "ff800000--ff803fff" by using a JTAG. Is there anything wrong in my config(in attachment) ?
