目前使用arm的ubuntu10.04版

版子接上Sata硬碟後，一直抓不到。

dmesg訊息如下

ata1.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen
ata1.00: failed command: IDENTIFY DEVICE
ata1.00: cmd ec/00:00:00:00:00/00:00:00:00:00/40 tag 0 pio 512 in
         res 40/00:00:00:00:00/00:00:00:00:00/00 Emask 0x4 (timeout)
ata1.00: status: { DRDY }

 

想請問是哪個地方出問題?

謝謝

針對這個問題, 以下是我的建議方向.

這個問題是 Host driver 想要下 IDENTIFY DEVICE command (0xEC), 但是 fail (timeout).

從這 log 來看, 只能看到說 Device 的 Status 不是在 ready 狀態 (正常的是要 0x50), 所以有問題. 

一般 driver 會再做 soft reset or hard reset, 如果再沒有用, 就把這個 port 關掉了.

造成這個問題, 有兩種可能性:

1. 最大可能就是 driver 與 這顆 arm 的 SATA controller 匹配性(相容性) 不好, 需要再 tune 一下 SATA driver.

    這個在 embedded system 是常會發生的. 一般 PC 就比較不會.

    如果換顆硬碟是 ok 的. 那就是 driver 需要針對這顆不行硬碟的 timing (wait or reset time 長度) 來調整.

    通常容量大的硬碟,一開始 initialized 的時間是需要比較長的, 尤其現在已經到一顆 1TB or 2TB, 甚至 4TB. 

2. 這顆硬碟可能有問題, 可以換顆硬碟試看看.

如果還有任何問題, 請再跟我說, 我們再研究看看.

 

先謝謝老師回應

 

我目前板子所使用的kernel都相同，有用ubuntu11.10的版本去測試，可以抓得到sata硬碟，而10.04版本卻抓不到

想問這樣是driver有問題還是有其他方面的問題?

硬碟也是使用同一顆再做測試。

 

謝謝

恩, 應該是 Ununtu 10.04 SATA driver 的問題, 如果 11.04 是 ok 的話.

有機會可以 diff 一下 code, 看看是哪邊造成的 (一般都是 reset or initialized timing 造成).

而且這顆硬碟也是比較古老了...SATA I (1.5G),  容量150 GBytes...^^

現在都是  SATA III 了.

 

老師我不懂您的意思，embedded的系統我兩邊都一樣的kernel版本，

kernel裡面所用的sata driver，應該也是同一隻?

還是ubuntu裡面也另有sata driver?

 

Sorry, 不是很懂你的測試環境, 先釐清一下

1. 你是說你用 PC 測試 (同一顆 HD), 在Ubuntu 11.10 是 ok, 在 10.04 是不行的.

所以測試環境有兩個平台, 一個是 PC, 一個是你的 arm 板子.

然後 PC 有用 Ubuntu 11.10 and 10.04 去測試, 那 arm 的 kernel 版本是??

我描述的對嗎?

 

老師我目前都是用arm的板子在測

arm kernel目前都用一樣2.6.35

 

但分別上了ubuntu11.10和10.04

其中11.10抓得到sata硬碟，10.04抓不到

 

所有測試都在arm的環境下

恩, 這就真的很奇怪了.....@@

你的 arm code 應該都是一樣的, 所以不管是在 Ubuntu 11.10 or 10.04, SATA driver 是相同的.

而且你在 Ubuntu 11.10 or 10.04 compile, 基本上灌的 cross compiler for arm 應該也是一模一樣的.

沒有理由在 11.10 可以, 但是 10.04 不行.

所以結論是真的很奇怪, 我不知道還有什麼是不一樣的嗎?

但是如果你在 11.04 可以的話, 你就先用 11.04 的開發環境好了.
