New ContributorMCIO to PCIe Host Adapter for Agilex 7 M-series Dev Kit
Hello,
I need help to choose the right MCIO cables and MCIO-PCIe Gen5 adapter to connect an Agilex 7 M-series dev kit to a host over CXL (Compute Express Link). The host is a Lenovo workstation featuring 2x Intel Xeon Gold 6416H (2x18-core, 45MB Cache, up to 4.20GHz) and 4 PCIe 5.0 slots.
Is there a recommended set of MCIO cables and MCIO-PCIe adapters that have been tested and with Agilex 7 M-series dev kit?
In theory, I should be able to use this MCIO-PCIe adapter together with two MCIO SFF-TA-1016 8i cables, but could find no cross reference to supported hosts and FPGA devices.
Thank you for your help,
Denisa Constantinescu

Hi Denisa,
The Agilex 7 I-series Dev Kit (2xR-Tile+1xF-Tile) MCIO connector can work with Amphenol cable P/N: HMC74-1492 in a PCIe Gen5 test. This is the only info I have so far. Hope this helps.

Jzone315Hi Denisa：
Have you tried this adaptor and cable you mentioned above，we looking for this adaptor too.
Regards and thanaks.

Hi Jzone315,
We tried the mcio-PCIe adapter but could not make the FPGA PCIe device visible from the host side. Unfortunately, Intel/Altera does not provide a PCIe design example for the Agile 7-M series, so we adapted the one available for the I series. Said this, I am not sure if the problem is the cables, the adaptor or the PCIe IP design.
Dear Altera/Intel Support,
According to the documentation ( https://www.intel.com/content/www/us/en/products/details/fpga/development-kits/agilex/agm039.html), a PCIe 4.0 Design example is provided, but I could not possibly locate it. Is there any chance there will be a reference design for using the PCIe on the Agile 7-M series dev kit? If not, is this still the official channel to get post-purchase support to help Altera FPGA users get the basics working?Thanks,
Denisa

Hi Denisa：
Yes，we tried this mcio-pcie adapter too, also failed to work, we are pretty sure that it is the problem of this adapter, but intel does not provide this adapter, nor does it provide a link to buy
ihsan28Hi All,
Have you got any updates or progress regarding the PCIe access for Agilex 7 M-series? I am starting work with that. Thank you.
