Hi, the hardware in question: PCIe_TO_2-CH_SATA_HAT+ In expectation for the Rock 4D forum to arrive I am posting my issue here: The Rock 4D works and all is well The two SATA drives work over USB to SATA adapters - that is not ideal in the long term IMHO The HAT just arrived and i have no doubt in my mind that it can be defective in any way - i assume it is 100% operational. But when i connect it and plug the power in the Rock 4D boots, everything else works as usual, but the HAT just sits there without any signal. My questions: 1. How do i query the eeprom via the pins 27 & 28 (ID_SD & ID_SC), do i just enable the i2c_6 overlay? 2. What then? I queried the ahci module with: `modinfo ahci` but it is both a built in and i suspect it does not support my device anyway? Looking forward to try help get this nice board supported on Armbian for other FPC equipped devices.

Cheers, will do!

Hello to everyone. Being new around here I figured to drop one message here first... So, i have this Radxa Rock 4D SBC and i am quite impressed with it Me being me and SBC being what it is, yada... yada, i now have this hat+ from Waveshare - it is an dual SATA to PCIe adapter. It was designed for the Raspberry pi 5 obviously but Radxa has since started putting those FPC connectors on and i really would appreciate a 24/7 NAS with a SBC footprint... Long story short, it does not work out of the box - i have no doubt the product is okay it's just the HAT fails to initiate the OS and register. It reportedly has an eprom with data on it but my guess is it has to have a dtb overlay active and my rock 4D lacks anything in that regard (a "sata" in the overlay name) My issues? 1. Where is the Rock 4D forum or where do i post this issue best to?
