Sector Protection Error when program flash on t4240qds

[p4080ds]

Hi,

   I tried to program nor flash on a t4240qds bareboard via CodeWarrior TAP, but got following error.

   I added an unprotect , an erase  and a program action. I'm sure the qds board is good.

fl::target -lc "test_RAM_T4240_Download"

fl::target -b 0x0 0x180000

fl::target -v off -l off

cmdwin::fl::device -d "S29GL01GP" -o "64Mx16x1" -a 0xe8000000 0xefffffff

cmdwin::fl::protect all off

I have the same problem. How can i solve it? I can erase flash, but i cant write data.

hello, do you solved this problem?  what reason causes this error?

Instead of adding Erase action for sector, you must use Program Action with Erase sectors before program.

Hi Adrian,

  Thank you for your patience to answer.

   I also tried the way which you metioned above, but still show me Sector Protection Error.This is very confusing. Is there any other helpful tips I missed?

        Thanks,

Did you check 'Restricted Addresses in this Range' option? Also, make sure you use the init when connecting to board.

Yes, I checked this option.

This option will restrict actions on that memory zone. You don't have to use this option, just use Erase before programming and eventually the Address Offset.
