A600 Pistorm, no HDMI output from the PI

[TommoLB]

I have an A600 with a Pistorm (Pi 3A installed) and other add ons (including rgb2hdmi) and it works nicely and I wanted to enable RTG on the PiStorm to display Workbench, play Doom etc.

I have a basic emu68 setup on the microSD card and it works great except that I get no signal at all from a HDMI cable plugged into the Pi. I had thought that until I did the work to enabled RTG in Amiga OS, I would get a white screen from the HDMI side with the words EMU68 on. Was I mistaken on this? If not, what might be the cause? Suffice to say I have tried multiple HDMI cables (although not another monitor).

My ultimate end goal (if this was realistic), was native Amiga output on RGB2HDMI, while the RTG would come out the Pi. I'd have both HDMI cables plugged into a HSMI splitter and would switch between them when needed. That was the plan anyway.

Does your PI 3B work as it should when not in the Amiga?

Good question. I got it especially for use with the PiStorm so never used it standalone. Will take it out tomorrow and test it.
p.s It's a 3A+ not a 3B as originally stated.

The Pi3A+ does appear to be faulty (a first when it comes to Pi's, I own dozens) as the same problem occurs when I tested it standalone. Now waiting on Amazon to deliver a replacement.

An update. After my replacement 3A+ had similar issues, I turned to config.txt file on the FAT32 partition on the SD card and noted one line hdmi_group=2 , with the comment line above "Comment out the hdmi_mode line if your monitor does not like it.". After doing this.... success the EMU68 screen appeared from the HDMI port.

Except.... the emu68 screen displayed when my setup was to boot to 3.2.2 from a CF card on the IDE port of the Amiga, but since I installed 3.2.2 onto the micro SD card in the Pi I get a black screen that eventually goes to no signal.

I suspect my monitor is not happy with something, which is a shame as it's a monitor with all the ports (HDMI, SCART, RF etc) so was my go to monitor for retro stuff. I plan on trying out a different monitor tomorrow to see what happens.

My alternative is to forget trying to boot off the Pi microSD card, run off the IDE port instead and get that configured to use RTG.
