## Summary I2C1 was mapped to PB12/PB13, which the QFN32 package on this board does not have. It now uses PB15 (SCL) / PA8 (SDA), and the bringup registers `/dev/i2c1`. Those pins are also the I2C0 fallback when SPI is on, so I2C1 is dropped from `periph`. Enabling both is a build error. The docs now cover the J4 caps (closed for the on-board GD-Link, removed for an external J-Link), the J5 console jumpers, and flashing with a J-Link. ## Impact Only the `gd32vw553k-start` board changes. `periph` no longer enables I2C1, which its bringup never initialized. ## Testing `periph` builds as shipped: ``` $ ./tools/configure.sh -l gd32vw553k-start:periph $ make -j ``` On hardware, `sht3x` plus I2C1, flashed with a J-Link, with a sensor at 0x44 wired to PB15/PA8: ``` $ ./tools/configure.sh -l gd32vw553k-start:sht3x $ kconfig-tweak --enable CONFIG_GD32VW55X_I2C1 && make olddefconfig $ make -j$(nproc) nsh> i2c bus ... -- This is an automated message from the Apache Git Service.
