Reference design does not appear to boot on Polarfire Discovery Kit

[klab-d]

I have reprogrammed the board with the reference design from here:

https://github.com/polarfire-soc/polarfire-soc-discovery-kit-reference-design/releases/tag/v2024.06

I have downloaded the prebuilt Linux Image for the Discovery Board from here:

https://github.com/polarfire-soc/meta-polarfire-soc-yocto-bsp/releases/download/v2024.06/core-image-minimal-dev-mpfs-disco-kit-20240703233429.rootfs.wic.gz

I have used USBImager to program the .wic file onto an SDCard.

The following output is seen on UART0

Somtimes I get the following on UART1:

** No partition table - mmc 0 **
Couldn't find partition mmc 0:1
ethernet@20110000: PHY present at 11
ethernet@20110000: Starting autonegotiation...

ethernet@20110000: link up, 1000Mbps full-duplex (lpa: 0x3c00)
BOOTP broadcast 1

But most of the time i get nothing all.

I have run the memory tests code which passes

Also having this exact same issue with multiple microSD cards.
