bsp, hil: flash WCH boards with the unified OpenOCD fork (#3791)

2026-07-28T05:50:28Z

bsp, hil: flash with the unified OpenOCD fork https://github.com/hathach/openocd (branch tinyusb) is mainline plus every config these boards need: RPi RP2350, ADI max32/max78, the MounRiver WCH configs, and the wlinke adapter on mainline's riscv target. It is a superset of the vendor forks, so one 'openocd' covers all boards; -DOPENOCD=/OPENOCD= still select another, msdk's when MAXIM_PATH is set. Drops family_flash_openocd_wch and the OPENOCD_WCH pair, dedups family_flash_openocd_adi, aligns ch583's work area, and points hil at the flasher's own config instead of generating one per probe. Verified: HIL green on all four WCH boards and max32666fthr.

dcd/ch32_usbfs: support CH32V103 combined endpoint control register

2026-06-18T03:58:58Z

CH32V103 uses the older USBFS IP: a single combined UEPn_CTRL register per endpoint (IN response in bits [1:0], OUT response in [3:2], shared auto-toggle, separate IN/OUT toggles) instead of the separate UEPn_TX_CTRL/UEPn_RX_CTRL bytes of the newer IP (CH32V20x/V307). The shared driver was written for the newer IP, so EP0 control transfers never worked on V103: the OUT response was written to a reserved byte and the IN write clobbered the OUT bits. - ch32_usbfs_reg.h: annotate the V103 register struct with byte offsets and add a union exposing the combined UEPn_CTRL at the UEPn_TX_CTRL offset; define CH32_USBFS_EP_CTRL_COMBINED and the combined-register bit positions. - dcd_ch32_usbfs.c: abstract EP control access behind ep_tx/rx_ctrl_set() (full write) and ep_tx/rx_set_response() (response-only RMW). The newer-IP path is unchanged; the combined path read-modify-writes the single register and arms the post-SETUP data stage at DATA1. - bsp/ch32v10x: implement board_get_unique_id() (real chip UID) and drop the CSR 0x800 writes that corrupted the QingKe V3 interrupt config and left all interrupts disabled (the USB ISR never ran). Verified on ch32v103r_r1_1v0: enumerates and passes HIL for cdc_msc, hid, msc, midi, mtp, dfu, etc. Co-Authored-By: Claude Opus 4.8 (1M context)
