LS1021ATWR : Sata Command Not Found In U-boot

[vigneshr]

Hi All,

I was trying use sata interface in ls1021atwr board for sdk 1.7, but it is showing sata command not found. Could someone help me how to enable/add the sata command in u-boot ?

Is there any macros should be added or any patch to be applied ?

Here is the u-boot log,

Hi Yiping,

Ya, I was able to see all those logs in my u-boot, but in kernel i want to access the hard disk. I done dmesg but hard disk is not detected there. How to resolve it ?

Thanks,

[artsiomstaliaro · Accepted solution]

Need to rebuild Linux kernel with:

1. In Kernel menuconfig Device drivers->Serial ATA and Parallel ATA

     [*] SATA Port Multiplier support

     <*> AHCI SATA support

     <*> Freescale 3.0Gbps SATA support

2. In Kernel menuconfig Device drivers->SCSI device support-> <*> SCSI disk support

3. In Kernel menuconfig File systems->

     <*> Second extended fs support
     <*> Ext3 journalling file system support

     Partition Types ->

     [*] Advanced partition selection

     [*] PC BIOS (MSDOS partition tables) support

     Native Language Support ->

     (iso8859-1) Default NLS Option

     <*> Codepage 437 (United States, Canada)

     <*> NLS ISO 8859-1 (Latin 1; Western European Languages)

Hi Art,

Thanks, now I'm able to detect hard disk in kernel. Now can you help me how to add SATA command in the u-boot. I have added SATA command in u-boot by adding some macros in ls1021atwr.h and config_cmd_all.h file from the u-boot source file. But I can able to use only sata command. Not able to use sata init , read, write etc. What could be the reason and solution for this issue.?

[artsiomstaliaro]

What should do 'sata' command?

For example, you have FAT on SATA HDD and you need to boot uImage from FAT partition.

So:

setenv sata 'fatload scsi 0:0 81000000 uImage'

[vigneshr]

Okay Art,
Thanks.

[artsiomstaliaro]

Hello,

please use "scsi scan" .

[vigneshr]

Hi Art,

Thanks,

With scsi scan i was able to detect the hard disk in u-boot, but in kernel i was not able to access the disk. what should be done to detect the device in kernel ?

and also please let me know how to add sata command in u-boot ..
