  • Programming the Spansion (S29AL016J) NOR flash using J-Flash

    Hi,



    I am using the J-Flash to program the external NOR flash which is the Spansion chip S29AL016J. The micro used is LPC2478.

    When I try to connect to the external flash which is connected to CS1, I get the following error.

    Can you please help me to flash the Spansion chip.

  • Hi,

    did you use the LPC2478_1x16_CFI.jflash sample project for reference in order to create your one?
    If not, please check the settings in the sample project with the settings in your project.
    The sample project is pre-configured to connect to external CFI-compliant NOR flash connected to CS0, so it will require small modification.


    Best regards
    Alex

  • Programming the Spansion (S29AL016J) NOR flash using J-Flash

    Hi Alex,

    I tried using the sample project LPC2478_1x16_CFI.jflash to flash the Spansion chip but still it says "it could not find any flash devices".

    Is there any other settings related to PLL which needs to be added to the CPU settings of LPC2478_1x16_CFI.jflash?

    I could see from the J-flash ARM documentation that the flash device S29AL016J has not been listed as supported chip.

    Can you please confirm if its possible to use J-flash for programming this NOR chip? Also from the datasheet of this NOR flash chip the device ID query seems to be different say it reads writes to address 0x555 instead of 0x5555. I have attached the command definition table for this chip for your reference.

    Thanks for your help in advance.Spansion_chip_command_definition_table.pdf
