    Hello Havi,
    Could you confirm that this sFlash device is from Spansion or Macronix?
    And further after flashing your application image (metaImage) to device and reset in SOP-4 mode, are you able to connect to R4F core from CCS?

    To make sure that AWR1642 bootloader reads FW contents from sFlash and put it on corresponding RAMs, please connect MSS core and look for '0x000000' address in CCS memory browser window. If that is non-writable then its ROM content, i.e. application is not loaded (bootloader doesn't recognized sFlash format).

    Hello Havi,
    As I assume you have custom AWR1642 board with sFlash(GD25B64CS2G) connected to it.
    Could you try this step once more-
    1. set device in SOP-5 mode and flash 'packages\ti\utils\ccsdebug\xwr16xx_ccsdebug.bin' file to awr1642 using UniFlash tool.
    2. After flashing is done switch to SOP-4 mode and reset.
    3. Try to write some value on '0x0000000' adress, if you successful that means bootloader is able to load MSS binary to RAM. Thus AWAR1642 detects sFlash Chip.

    You should able to connect MSS core over JTAG in SOP-4 mode (ROM content on '0x0' location: non-writable) even if bootloader invalidate sFlash chip and ignores reading its content.

    Please refer this e2e link which discuss about sFlash compatibility.
