we designed a board with P2020 processor!

the nor flash is s29GL256p, we cann't flash into it a bin file ,we can even not erase the chip:

we use codewarrior 10.3. in the flash programmer,we select  erase whole device. it completed with errors!

the print is as follows:

fl::target -lc "LC for Simple Flash"

fl::target -b 0x2000 0x30000

fl::target -v off -l off

cmdwin::fl::device -d "S29GL256P" -o "16Mx16x1" -a 0xfe000000 0xffffffff

cmdwin::fl::erase all

Beginning Operation ...

by the way we use CPLD to latch the multiplexd LAD0~~LAD15 address to Nor.

Hello Li Tian,

Probably problem exists in DDR controller configuration, please enable "Verify Target Memory Writes" in PA Flash Programmer Task panel, if the memory type error is encountered, please try to use SRAM initialization file in Freescale\CW PA v10.3\PA\PA_Support\Initialization_Files\QorIQ_P2.


Have a great day,
Yiping
