SATA and kernel 3.4.75
Hello all
I am testing a SATA hard disk with Olimex A10-LIME board. It works correctly, but if I disable the sunxi_nand driver in the kernel configuration, SATA stops working with error:
[ 66.033059] ata1: SATA max UDMA/133 mmio [mem 0x01c18000-0x01c18fff] port 0x100 irq 56 [ 66.393493] ata1: SATA link down (SStatus 0 SControl 300)
What is the dependency on sunxi_nand ? What if I want to use mtd + SATA ?
Best regards
mtd requires mainline kernel, so that's a non-issue As for nand +sata requirements, that's strange, maybe something else got disabled aswel?
Recompiled with SUNXI_NAND as a module. Tried loading sw_ahci_platform first and nand after This is what I get:

After loading nand, SATA link is restarted and hard disk is properly recognized. Any ideas ?
can you paste somewhere (sprunge.us?) the deserialized fex of the script.bin you are using?
I do have to ask you to upgrade to the latest 3.4 series as 3.4.75 is pretty ancient!
Updated to 3.4.79. Same happens. I believe other people on Olimex forum have also verified this behavior. My config for 3.479 is here http://sprunge.us/BhXh
the sata_para section of your .fex doesn't include any of the needed pinmixes
My script.fex is based on Olimex one. Documentation on http://linux-sunxi.org/Fex_Guide#.5Bsata_para.5D only mentions:
[sata_para] sata_used = 1 sata_power_en = port:PB08< 1 >< default >< default >< 0 >
Can you tell me what else is missing ?
