Add new HIC stm32f723 request

[RadioOperator]

Dear Sir,
The famous stm32f103xb in DAPLink very long time, but it's only USB full-speed capability and limited Flash. Recently, I have finished 1st test version CMSIS-DAP v1 & v2 on STLINK-V3MINI device. Refer to
https://github.com/RadioOperator/CMSIS-DAP_for_STLINK-V3MINI
It's a new lower cost USB 2.0 high speed hardware board, everything ready to go DAPLink.

Would you help to port the STM32F723 into DAPLink HIC list? or any tips.

If you can be more specific, we might help you.

0xc0170, I'm trying to port the IC interface drivers based on stm32f103xb. With your supporting, would be successful definitely. The STM32F723 has 216MHz core Freq. and USB high-speed, would be the best DAPLink device. I'm not full-time to do this, please wait. If I got something cannot solve by myself, I will let you know. Thanks.

Hi, 0x0170, because the latest STM32F7 series USB driver worked for RTX5/CMSIS and ARM RL-USB (2019), according to the info in #197, I think it's better to wait the official RTX5 DAPLink release, then add STM32F723 as new HIC should be very easy, I hope the new release shares the same API with the latest version RL-USB and Keil/MDK-Middleware.

Hi ! Seems like this issue could be re-opened ?

Hi @vincent290587 are you (or @RadioOperator?) interested in working on this project? Since the issue was closed a lot of things have progressed: DAPLink was ported to GCC and RTX5. The main hurdle remaining is the USB driver but there are resources available:

• Keil opened the drivers for STM32F4xx and that was used as a basis for the stm32h743xx HIC.
• The CMSIS USB drivers (CMSIS/Driver/USBD_HS_STM32F7xx.c) in the Keil STM32F7xx_DFP CMSIS pack, but it is designed for a newer driver API, so it can't work as-is.

For anyone interested in working on this, I can point to a branch that has a lot of the foundational work, including some partially working USB driver (at Full-Speed, no High-Speed).

I could possibly do it somewhere in the next year as part as another project, but the timeline is not sure.

[vincent290587]

That being said I would be very glad if you could point me to that branch !

[mathias-arm]

I have a branch with multiple STM32 targets (they all share the same USB driver for USB OTG): https://github.com/mbrossard/DAPLink/tree/feature/stm32_otg_usb (this branch is rebased very often).

I have started some work to port DAPLink to STM32F723, but could you answer some questions ?

• how did you generate the flash_blob.c ?
• Which USB drivers are you using ? (I am using those in the hic_hal/stm32/shared folder)
• I managed to get the bootloader to a point where there is "some" USB activity (until I tget invalid USB BOS descriptor), could you advise on USB debugging tools ?

In any case many thanks for the code
