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
