  • [SOLVED] WCH CH32V J-Link support

    It'd be great to get J-Link flash programming support for WCH's parts — for example, the CH32V307: github.com/openwch/ch32v307/tree/main/Datasheet

    These parts are basically STM32 clones (but with RISC-V cores), so they come with a ton of peripherals (lots of industrial-control-oriented timers and such). The stand-out feature is the USB 2.0 HS and 10M ETH PHYs built-in.

    A cursory glance at the CH32V307 datasheet indicates their flash memory controller has a nearly-identical interface to the STM32F1 (seems to match the data from ST's app note PM0075). I wouldn't be surprised if all their MCUs used an identical programming model.

    WCH sells dev boards and samples through LCSC:

  • Hi,
    Thank you for your inquiry.

    Support for these devices is already on our ToDo.
    Unfortunately, we can not yet provide a fixed timeline for when support is added,
    as the next couple of weeks are already fully booked with projects.

    If you would like to be informed when support is available,
    I would recommend you to subscribe to our news letter.

    Stay up-to-date regarding J-Link:
