J-Flash init sequence for ARM1136 core with Spansion external flash

  • J-Flash init sequence for ARM1136 core with Spansion external flash

    Hello,

    I am working on a platform with an ARM1136 core (Mindspeed M83263G) and Spansion flash (S29GL256P). I am not able to get the flash detected correctly. I have seen other threads on the forum for ARM7/9 cores with Spansion that pointed to the CPU init sequence, but those tip did not lead anywhere for me. J-Link detects and correctly identifies the core. It seems to be able read individual memory addresses from the address space of RAM. But it looks like it can not put the processor in halt.

    Does anybody have experience working with ARM11 cores and J-Flash. I am not an expert in using JTAG and any suggestions/pointers would help.

    Thanks in advance.

    Hi Guen,

    Did you set up the EBI correctly with proper timing parameters for the Flash?

    When you saw the Flash was not detected properly, did you get any log information?

    Thanks,
