I’ve been happily playing with the pre-built images on my recently received rev2.1 clearfog, and I’m struggling a bit to build a new image with a different SERDES config that enables QSFP and SFP+
- I have a QSFP-SFP28 converter which puts 25Gb on channel 0. Can I use something like SD1=21 to enable two of the SFP+ ports, and still have functional QSFP at 25Gb? or does a converter only work with SD1=13,14 and fallback to 25Gb compat?
- I would have happily tested all this already, but it seems I cannot build bootable sd images with either
buildgithub projects. I’ve tried baremetal, baremetal on aarch64 thunderX2, and dockerized (both x86 and aarch64 native). The images that are produced look sane to me: same size and similar contents as those provided by solidrun, but when I try and boot them, the clearfog board seems to sit in an unhappy boot loop cycling power every second. Am I missing something here?
Does anyone have tips for producing functional images from github, or would be willing to post a few UEFI images with different SERDES configs for us clearfog users?
