"strange" First Stage Bootloader effect

Hello everyone,

I did an experiment with the Zynq TRD Version 14.4 and version 14.5 on the ZC702.
I used the First Stage Boot Loader (FSBL)of the TRD Version 14.5 for the TRD 14.4. Kernel, devicetree, bit file, u-boot etc. are from TRD 14.4, the FSBL is from the 14.5 TRD.
My system is booting, the fpga is programmed, the rootfs is mounted, everything seems fine but I don't see any output over the HDMI connector. Now I am a little confused, in my opinion the FSBL is just responsible for programming the FPGA and starting u-boot. What influence can it have on the hdmi output resp. the framebuffer device.

 

best regards,

Matthias
