Ti8168+DVRRDK_04.01.00.02 mobile hard disk access

bingyi cheng

hi all:
Ti8168+DVRRDK_04.01.00.02 mobile hard disk access, to test the speed of writing, only 4.8M/s, TI81XX_PSP_04.04.00.02_Feature_Performance_Guide.pdf,
this file is written to load the g_file_storage.ko, do not know whether to help write speed.
In addition, I can not compile and generate g_file_storage.ko in this platform, is there a specific menuconfig configuration. Thank you!

Bingyi,

Please provide me the output of the below command?

host:.../linux-dvr-rdk-dm81xx$make help

Which defconf file you are using? Which tool chain you are using?

It seems to me that you did not export the ARCH.

Can you provide me the output of the below commands:

root@root:/DVRRDK_04.01.00.02/ti_tools/linux_lsp/kernel/linux-dvr-rdk#echo $ARCH

root@root:/DVRRDK_04.01.00.02/ti_tools/linux_lsp/kernel/linux-dvr-rdk#ls -al

Do you have DM816x TI EVM or DM816x DVR board or custom board?

Pavel

Hi Bingyi,

bingyi cheng said:

You mean that you are making the linux kernel with the below commands?

root@root:/DVRRDK_04.01.00.02/ti_tools/linux_lsp/kernel/linux-dvr-rdk# make ARCH=arm CROSS_COMPILE=arm-arago-linux-gnueabi- distclean

root@root:/DVRRDK_04.01.00.02/ti_tools/linux_lsp/kernel/linux-dvr-rdk#make ARCH=arm CROSS_COMPILE=arm-arago-linux-gnueabi- ti8168_dvr_defconfig

root@root:/DVRRDK_04.01.00.02/ti_tools/linux_lsp/kernel/linux-dvr-rdk#make ARCH=arm CROSS_COMPILE=arm-arago-linux-gnueabi- uImage

And with the generated uImage, the USB U-Disk is working fine? Do you plug the U-Disk before power on the board or you are making hot-plug?

Can you provide me the exact commands you are using here?

the default menuconfig mean that ti8168_dvr_defconfig is not changed,and keeped orginal .

in /DVRRDK_04.01.00.02/ti_tools/linux_lsp/kernel/linux-dvr-rdk ,
we used the cmd "make menuconfig ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- ti8168_dvr_defconfig" to changed menuconfig

we enter /DVRRDK_04.01.00.02/dvr_rdk ,and "make lsp" to generate uImage。

with the default menuconfig,we could find U-disk deivce /dev/sdb1,but with gadget Mode,and cold-reset our ti8168-board, we could not find U-disk device。

with default menuconfig,the write speed is only 4.8MB/s.Is this status normal?
I want to know whether g_file_storage.ko could help U-disk write speed.

Bingyi,

ti8168_dvr_defconfig should not be changed in all the cases, you should aways keep it original. The file that is to be changed is .config

Can you try with the below sequence? What is the result?

root@root:/DVRRDK_04.01.00.02/ti_tools/linux_lsp/kernel/linux-dvr-rdk#make ARCH=arm CROSS_COMPILE=arm-arago-linux-gnueabi- uImage

For changing the .config file through menuconfig, try with the below sequence:

root@root:/DVRRDK_04.01.00.02/ti_tools/linux_lsp/kernel/linux-dvr-rdk# make ARCH=arm CROSS_COMPILE=arm-arago-linux-gnueabi- distclean

------> change USB settings here

Do you connect the u-disk before power the board or you connect the u-disk after power on (hot plug)?

Pavel

Check the u-disk datasheet, check what is the supported speed there. From DM816x side, we have higher than 4.8MB/s in the performance guide.

When DM816x USB is host, when FS is ext2, the speed is around 23MB/s, when FS is VFAT, the speed is around 18MB/sec. What is the FS (file system) of u-disk?

When DM816x USB is gadget/device (g_file_storage.ko is used), write performance is 30MB/s, read performance is 40MB/s.

Make sure you have all the USB related patches of the below linux tree in your code base.

Pavel
