C28346 SDFlash Utility Programming

I am having an issue programming my FLASH device via SPI from the SDFlash utility. I updated the algorithm project so that it works correctly with my FLASH chip and have verified that I can successfully program a test image that blinks an LED on the card. My issue is when I try to program an image that is large enough that it gets to address 0xf800. Any image that is small enough to fit under 0xf800 programs successfully.

Has anyone seen this issue before or had any similar issues with the SDFlash utility?

    I also have the same issue. I am interfacing c28346 with AT25DF161A SPI-Flash chip. I have downloaded the SDFlash algorithm files and executable, then updated the algorithm files to specify the available memory (2 Mb's) and last address (0x1FFFFF) in accordance with chip manual. However when erase/program/verify, erase is succeeded but then I am getting the error message saying "Program Failed at address 0xF800". When I decrease the size of the code slightly under 0xF800, I don't get any errors and get my project working.

    Does anyone know reason of this issue, and how can I solve it?

    Hello All,

    I have exactly the same problem. I've been struggling for a week on it, but no solution so far.

    I wrote to Spectrum Digital as well, but they say that they do not support external flash!

    Has anyone figured out the cause of this problem?

    Any help would be appreciated.
