STM32MPU Flashing fails: Error: File does not exist Distribution-Package/build-openstlinuxweston-stm3
I followed the instructions on https://wiki.st.com/stm32mpu/index.php?title=STM32MPU_Distribution_Package&sfr=stm32mpu to flash my build image on my STM32MP15. After step 6: Where I build the image with the command "bitbake st-image-weston" I go to "STM32MPU-Ecosystem-v5.0.0/Distribution-Package/build-openstlinux-weston-stm32mp15-disco/tmp-glibc/deploy/images/stm32mp15-disco/flashlayout_st-image-weston/optee/FlashLayout_sdcard_stm32mp157f-dk2-optee.tsv" (From Developer Package (SDK) have been built for this st-image-weston image in the documentation). When I tried to flash it to the board with "STM32_Programmer_CLI -c port=usb1 -w FlashLayout_sdcard_stm32mp157f-dk2-optee.tsv" I received "Error: File does not exist: /home/nesnes/STM32MPU-Ecosystem-v5.0.0/Distribution-Package/build-openstlinuxweston-stm32mp15-disco/tmp-glibc/deploy/images/stm32mp15-disco/flashlayout_st-image-weston/optee/st-image-bootfs-openstlinux-weston-stm32mp15-disco.ext4 Error: TSV flashing service failed"

Even though the file I want to flash is in the "STM32MPU-Ecosystem-v5.0.0/Distribution-Package/build-openstlinuxweston-stm32mp15-disco/tmp-glibc/deploy/images/stm32mp15-disco/flashlayout_st-image-weston/optee/FlashLayout_sdcard_stm32mp157f-dk2-optee.tsv" directory, I am receiving an error for "STM32MPU-Ecosystem-v5.0.0/Distribution-Package/build-openstlinuxweston-stm32mp15-disco/tmp-glibc/deploy/images/stm32mp15-disco/flashlayout_st-image-weston/optee/st-image-bootfs-openstlinux-weston-stm32mp15-disco.ext4"
What is the cause of this error and how can I fix it?
