Nor flash(pc28f128p33)

Hi all,

I am using ADSP-BF609 evm board.

I am trying to erase the sectors in nor flash by using pc28f128P33_Control( CNTRL_ERASE_SECT, &pCmdBuffer );  i can able to erase sectors after this erasing able read and write into nor flash.Then i tried to erasing entire nor flash by using pc28f128P33_Control( CNTRL_ERASE_ALL, &pCmdBuffer ); after running this command i could not able to operate any operations on nor flash like read,write and erase. I am using example for nor flash from power-on-self-test. 

could anyone help me to solve this issue?

Thankyou,

Regards,

Sravanthi

    Can you please provide more information on below points to assist you better on this.

    1) Are you getting any error while trying to read, write and erase the flash after "erase all"?
    2) You mentioned "can able to erase sectors after this erasing able read and write into nor flash", please let me know which sector you have erased? Are you able to read/ write the sector which you erased?
