imx6ull uboot startup

designteam — Thu, 29 Oct 2020 13:35:14 GMT

i have a boad based on a imx6ull but so far i cant get uboot running. the pc detects imx6ull via the uuu.exe app and it seems to complete the first stage of the programing but then hangs, i have it set in boot from uart mode and checked rails/clks/rst etc all looks ok

has anyone seen this before? log from uuu.exe is below any idea where to look?

uuu.exe -b qspi u-boot-qspi1-2020.04-r0-no-ethernet.imx
uuu (Universal Update Utility) for nxp imx chips -- libuuu_1.4.43-5-ga0b566d

Success 0 Failure 0

1:3 1/ 1 [=================100%=================] SDP: boot -f u-boot-qspi1-2020.04-r0-no-ethernet.imx

verbose mode gives
