Hello all,
I'm working with u-boot 1.2.0 on a board with MPC8xx processor and Intel Strata Flash Embedded Memory (I28F128P33B) mounted. Up to now I am trying to read the Device Identifier Information with the Abatron BDI2000 but I am a little bit confused. In fact I have the following output on the display
NEW_CCM_LC>mdh 0x40000000 40000000 : 0089 8821 0001 0001 0089 bfcf 0001 0001 ...!............ 40000010 : 0089 8821 0001 0001 0089 bfcf 0001 0001 ...!............ 40000020 : 0051 0052 0059 0001 0000 000a 0001 0000 .Q.R.Y.......... 40000030 : 0000 0000 0000 0023 0036 0085 0095 0008 .......#.6...... 40000040 : 0009 000a 0000 0001 0001 0002 0000 0018 ................ 40000050 : 0001 0000 0006 0000 0002 0003 0000 0080 ................ 40000060 : 0000 007e 0000 0000 0002 0000 0000 0000 ...~............ 40000070 : 0000 ffff ffff ffff ffff ffff ffff ffff ................ 40000080 : ffff ffff ffff ffff ffff ffff ffff ffff ................ 40000090 : ffff ffff ffff ffff ffff ffff ffff ffff ................ 400000a0 : ffff ffff ffff ffff ffff ffff ffff ffff ................ 400000b0 : ffff ffff ffff ffff ffff ffff ffff ffff ................ 400000c0 : ffff ffff ffff ffff ffff ffff ffff ffff ................ 400000d0 : ffff ffff ffff ffff ffff ffff ffff ffff ................ 400000e0 : ffff ffff ffff ffff ffff ffff ffff ffff ................ 400000f0 : ffff ffff ffff ffff ffff ffff ffff ffff ................
On the Intel Strata Flash Embedded Memory (P33) is written that at offset 0x10 I should find thw CFI Query identification string but, As you can see, I have them at offset 0x20. Anyway, after the unlock of the flash and the erasing I tried to load a u-boot 1.2.0 generated for the board and was loaded correctly (I read back the u-boot label at the beginning of the flash). The problem is that it doesn't start. Does anyone know if there is a u-boot code available to manage this kind of flash?
Thanks in advance
