Preface
This manual describes how to use the C3V-W Evaluation Board (EVB). This evaluation board is used for IP verification and software functions testing of the C3V-W chip. IP verification includes all IP tests in the chip, chip boot modes test, all GPIO, DVIO pins (UART, I2C, SPI, …) testing and multiplexed functional pins test, USB2.0, USB3.0, CPIO, MIPI/CSI-RX2, MIPI/CSI-RX3, MIPI/CSI-RX4, MIPI/CSI-RX5, MIPI/DSI-TX, and MIPI/CSI-TX and other interface tests. Software functions include i-boot, x-boot, U-Boot, TF-A, OP-TEE, FreeRTOS, Linux, Ubuntu server with MATE desktop and other related application tests.

Voltage of VDD_DVIO_2 | J61 |
1.8V | |
3.0V |
5.6 Additional note
Please note that for GPIOs that support dual operation voltage of 1.8V and 3.0V, in addition to configuring the power supply in the hardware, the software also needs to set the MS control bit to get the correct bias voltage.
i-boot will set MS control bit for boot devices if you set jumper J73 correctly.
