Ok thanks - I'll give it another go, although I thought it would be up to date as it was a fresh download of everything to a new memory card.
The current (v1.5.1) image was released on 2nd September 2019, and ships with a
4.19.67.20190827 kernel.
The kernel and boot firmware have been updated several times since then. So if you write this image, boot it, and then perform the update as described in my post
above, you should be good to go.
If your particular monitor is flashing
right from the first usage under v1.5.1 Gentoo however, you might need to temporarily connect it to another monitor / TV, so you can see the screen / perform the kernel update. Alternatively in this case, you can set a 'safe' mode temporarily, by editing config.txt in the first partition (which can be done on any PC) and uncommenting the following hdmi_group and hdmi_mode lines, so they read:
Code: Select all
# uncomment to force a specific HDMI mode (this will force VGA)
hdmi_group=1
hdmi_mode=1
Or alternatively, uncomment the
hdmi_safe setting in that file, as follows:
Code: Select all
# uncomment if you get no picture on HDMI for a default "safe" mode
hdmi_safe=1
Either approach should give you a
very clunky-looking VGA display, but should also work on just about any external monitor, and you'll at least be able to get in, start a console, and update the kernel and boot firmware as described. Once that's done, you can reboot and then run the bundled GUI tool (Applications -> Settings -> RPi Config Tool) to choose an appropriate resolution.
(For avoidance of doubt for anyone else reading this,
most monitors appear to work fine under the shipped v1.5.1 kernel and boot firmware, it is just a few where an update like this is required.)
best, sakaki
