I’m having trouble getting a new HiFive Unmatched board to boot. The SD Card that arrived with it was defective, so I transferred the latest image from Releases · sifive/freedom-u-sdk · GitHub to a fresh micro SD card using rufus. However, it still won’t boot.
I’ve tried the latest image (demo-coreip-xfce4-unmatched-2021.06.00.rootfs.wic.xz), the image it was packaged with (demo-coreip-xfce4-unmatched-2021.03.01.rootfs.wic.xz), and an Ubuntu image (https://cdimage.ubuntu.com/releases/21.04/release/ubuntu-21.04-preinstalled-server-riscv64+unmatched.img.xz) all with no success.
I’m getting some strange characters on the serial console at baud rate 115200 and an error message of 1 at baud rate 89856 (as the SW manual suggested in Chapter 8, section 1).
The MSEL switches are all set to the proper positions.
Any ideas what might be causing this problem?
