[OpenOCD-devel] writing to stm32h7 flash

[Matt S. <mat...@at...>]

Hi,

I have an issue using openocd with the STM32H753 processor.
I am using build openocd-0.10.0-12-20190422 on windows from
https://gnu-mcu-eclipse.github.io/blog/2019/04/22/openocd-v0-10-0-12-20190422-released/

When I try to program the device I get the following output:

I am calling openocd with the following options:
-f interface/ftdi/olimex-arm-usb-ocd-h.cfg -f
interface/ftdi/olimex-arm-jtag-swd.cfg -f target/stm32h7x_dual_bank.cfg

I think the same issue has been resolved elsewehere but I am still seeing
the issue with openocd. See http://www.openstm32.org/forumthread7464

Do you have any suggestions on how I can get this to work?

Best regards,
Matt
