Secondly I tried to generate similar patches for Kirkwood
oneprd_base (attached) on the top of this patch series
But somehow "ide reset" is unable to detect device on port. If you have openrd_base board, can you pls give a try?
May be you may need to look at mpp config.
I have an OpenRD Client, not base; client has a SATA connector to which I have a disk connected, so I could give it a try but we'll need to make sur how many SATA ports kirkwood has and which ones are used on either openrd client and base (orion5x has two sata ports and edmini uses port 1, not 0, for its sole SATA conector). I am away from home right now, but I will be able to give it a try as soon as August 1st.
Hi Albert Ping ...if you are back
I am, and I have done some work on your problem, but for the moment I am still at the same stage as you -- a continuous sequence of dots when doing an ide reset, right?
I have #define'd DEBUG in cmd_ide.c and compared the debug messages for my ED Mini V2 (working) and my OpenRD-Client (not working). I have also performed manual SATA and IDE reset sequences. Short story:
1) the board code correctly initializes the SATA link, which correctly detects a disk if there is one:
Marvell>> md.l f1082300 4 f1082300: 00000113 14010000 00000300 010300b0 ................ Marvell>> md.l f1084300 4 f1084300: 00000000 00000000 00000300 010300b0 ................ Marvell>>
(this is consistent with my system which has a 1.5 GBps disk on port 0).
2) The problem is that the drive appears continuously non-RDY (SStatus register remains at 0x80 while on the ED Mini V2 it ends up at 0x50, which basically means it is ready).
I will now compare the MPP / GPIO settings performed by the FLASH-resident U-Boot (its 'ide reset' command works ok) to those in effect when the patched u-boot fails. Maybe one GPIO controls power to the internal SATA port, although I doubt it -- if the drive was off, the controller would not see it at all, and SStatus at F1082300 would not report it present.
Pls include my email address in your white list, the mails to you bounces back to me.
It's not an issue of (not) whitelisting your e-mail address; it's your mail server being blacklisted by my email provider. If you have a recent non-delivery report please send it to me in private to my gmail account (albert.aribaud@gmail.com), I'll try to sort things out and contact your mail server's admin with the relevant details.
