Hi,
Starting a new thread based on previous success
We're porting our camera sensor (V4L2 subdev, I2C) and DSI panel + touch drivers — modules build fine against your SDK's kernel-devsrc. Curious what your recommended route is for...

Hi Greg,
Flashed the prelim build today — mostly excellent news, one blocker on the headline feature:

Hi David,
Sounds good! Keep me posted if you run into any major issues or inconveniencies (e.g. one thing I forgot to mention is that the prelim build was built with a lot of debug options enabled, so boot times etc are much more ver...

Hello,
I am sorry for the inconvenience.
You should be able to use this device instead of a Blaster device if that is a problem:

Thank you for pointing out the issue. The link suggests to program the QSPI NOR via Altera USB-II Blaster.

MW 10:23 AM MitySBC-Agilex5 FPGA Development: RE: rbf files from example project gives Error while booting
Hello,
The likely issue is that you need to reprogram the SDM and uBoot portion of the bitstream in the SPI NOR FLASH.
There can be an issue where the SDM / and initial bitstream build must match the targeted core.rbf file. If the...

Yes, actually this script A5ED065BB_mesh.pfg - worked.
I've created programming files and was able to boot.
And it is strange that the error message disappeared.
Thanks for your help!!!

Hi Mike,
For Rootport, we generally expect PERSTn for RP to come from FPGA IO driven by BMC on boards as shown below (just an example). So I am looking for logic on board that drives PCIe RP and EP PERSTn.
