Hi, I see ont he wiki that this boar might be compatible with PMP. I try to follow the same procedure describe in the wiki (cancelling the NO_PMP costant from sunxi_ahci.c but seems nothing happend. Any suggestion?
I’m also looking for PMP on the M2U. If someone could help us I would be very thankful!
we not test this function;
below is allwinner document about sata.
188.8.131.52. SATA • One SATA Host controller • Supports SATA 1.5Gb/s and SATA 3.0Gb/s • Compliant with SATA spec 2.6 and AHCI Revision 1.3 specifications • Supports external SATA(eSATA) • Supports power management features including automatic Partial to Slumber transition
you can check dirver ,it not support PMP
No, that method only works with kernel version 4.x+
R40 is just quad core version of A20, so I guess recompiling kernel will work… Maybe?
I need support for kernel 4.x cause I’m planning upgrading my NAS, but for months, still Sunxi is saying it is under work in progress.
