I am having issues programming my 32GB+ Flash Device with STM32CubeProgrammer

We have seen an issue when trying to program Flash devices that are above 32GB with the STM32CubeProgrammer.  The following steps outline the procedure that was used to program a 128GB SD card on the OSD32MP1-RED platform.  You will need to modify for your situation.

1. Use existing Cube Programmer + Flashalyout combination to just flash FSBL1 and FSBL2 partitions. You can use the attached Flashlayout file “FlashLayout_emmc_stm32mp157c-osd32mp1-red-trusted_boot.tsv” as reference.

2. Use the attached Flashlayout file “FlashLayout_emmc_stm32mp157c-osd32mp1-red-trusted_user.tsv” and attached “create_sdcard_from_flashlayout.sh” to generate a raw image for remaining partitions FIP + ROOTFS + USERFS + VENDORFS. The output will be named “FlashLayout_emmc_stm32mp157c-osd32mp1-red-trusted_user.raw”

3. Change the name of the output file from “FlashLayout_emmc_stm32mp157c-osd32mp1-red-trusted_user.raw” to “FlashLayout_emmc_stm32mp157c-osd32mp1-red-trusted_user.bin”

4. Now use the attached Flashlayout file “FlashLayout_emmc_stm32mp157c-osd32mp1-red-trusted_user_raw.tsv” with Cube Programmer: “STM32_Programmer_CLI -c port=USB1 -w flashlayout_octavo-image-weston/trusted/FlashLayout_emmc_stm32mp157c-osd32mp1-red-trusted_user_raw.tsv”. This will program a binary image that contains partitions FIP, ROOTFS, VENDORFS and USERFS to the eMMC without running into an error.

5. Since you now have all the partitions needed on the eMMC, you should be able to boot from the eMMC.
