Can read/write internal flash but can't with external

Staff: Johnny N.

  • I have a custom circuit use MPC5566 with flash s29al016j addr11 to 31, CS0,WE0,OE.
    I use PE multilink universal with Proppcnexus programer V6.71.00.00, it can detect MPC55XX and read/write internal flash with Freescale_MPC5566_1x32x768k_Freescale_H7F_32_Driver.PCP programming algorithm.
    I try to load Spansion_29AL016J_01_1x16x1meg_Qorivva.PCP programming algorithm, the programmer loading done and can show module data but all data is zero.
    I use oscilloscope to debug CS0,WE0,OE pin,all pin alway logic high don't change although Programmer show reading with addr increment.
    I try to load another algorithm but the same.
    Any one have some idea.
