Trouble Flashing STM32DDRFW-UTIL over USB
Background:
I'm trying to bring up a custom board with an STM32MP157D and DDR3. When I tried flashing the BSP, I got an error: "ERROR: DDR addr bus test: can't access memory @ 0xc0000004". I decided to try using STM32DDRFW-UTIL to test the DDR before proceeding. I downloaded the code and compiled and debugged the project for an STM32MP157C-DK2. The image sucessfully loaded via the ST-Link in engineering mode and I saw the UART with the expected DDR tool interface. My custom board does not have an ST-Link connection, so I was going to try to flash the image into sysram using USB. I'm still working with the DK2 as a proof of concept.
Issue:
When I try to flash the image using STM32_Programmer_CLI, the utility does not start. I am using the binary in the Binaries folder of STM32DDRFW-UTIL and trying to flash it with "STM32_Programmer_CLI -c port=usb1 -d STM32MP157C-DK2_DDR_UTILITIES_A7.stm32 0x01 -s 0x01". I get the following output and nothing on the UART:

How can I get this working? For reference, I'm running this on Linux.
Thanks for any help!
