Description

upgraded successfully to core 9

but when powering on the board, the ExclairXL boot one out of six times..
when it does not boot i get a message on the screen "image out of range" on my VGA screen and no Signal on HDMI

Its either board-board instability due to small timing differences or the new input pins I guess.

Can you check the voltage on these pins on PBI? They should all be 5V, I'm wondering if some are not pulled up. I guess I need to double check I put the correct pin for them in the .qsf file too!

Though thinking some more if you get 'no sync' then that is before all the new logic starts, so more likely the build-build instability on some boards only.

One thing to try, can you see if it's the same with a few different power supplies?

#7 Updated by ndary over 4 years ago

i did with same result, can anyone else confirm that core 9 works on on his v2 board?

Thanks for checking Nir. I guess it must be on the 'edge' and thus some boards work and not others. Its working well here, until I run Numen or try to use the internal freezer. They are real logic bugs though rather than a stability thing.

Just wanted to say that so far core9 has been working fine for me.

this happen on every core after flashing, to solve it i simply remove and put back the SD Card and it works
