LS1021ATWR : Sata Command Not Found In U-boot

vigneshr — Tue, 09 Jun 2015 13:21:49 GMT

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 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 ..

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,

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.?

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'
