Hi everyone,
I managed to get SDP protocol to work with on my custom i.MX6 board, so big thanks to Stefan for your work!
I'm now trying to load swupdate ramdisk with u-boot sdp command, without success. Is it a possible use case ?
Yes it should work, we use the U-Boot sdp command to download a squashfs based ramdisk in our Toradex Easy Installer: http://developer.toradex.com/software/toradex-easy-installer
Here my steps:
In u-boot: => sdp 0
On Host, $ imx_usb
config file <C:\Users\vpr\IMXUSBLOADER2\delivery\imx_usb.conf> vid=0x15a2 pid=0x0061 file_name=mx6_usb_rom.conf -> vid=0x0525 pid=0xb4a4 file_name=mx6_usb_sdp_spl.conf vid=0x0525 pid=0xa4a5 file_name=mx6_usb_uboot.conf config file <C:\Users\vpr\IMXUSBLOADER2\delivery\mx6_usb_uboot.conf> parse C:\Users\vpr\IMXUSBLOADER2\delivery\mx6_usb_uboot.conf Trying to open device vid=0x0525 pid=0xa4a5......................... Could not open device vid=0x0525 pid=0xa4a5
Is VID/PID showing up in Device Manager?
We did saw some problems with certain USB host implementation, so it might be a device dependency... I would also try a different machine/maybe Linux machine...
VID/PID in imx_usb.conf are correctly detected, and correct configuration file is launched (mx6_usb_uboot.conf), it contains:
mx6_usb_sdp_uboot hid,1024,0x10000000,1G,0x00907000,0x31000 test.txt:load 0x12100000
My imx_usb.conf is the following:
#vid:pid, config_file 0x15a2:0x0061, mx6_usb_rom.conf, 0x0525:0xb4a4, mx6_usb_sdp_spl.conf 0x0525:0xa4a5, mx6_usb_uboot.conf
Yeah assuming you use the Toradex branch of imx_loader currently this should work.
Our script looks like this: mx6_usb_sdp_uboot #hid/bulk,[old_header,]max packet size, {ram start, ram size}(repeat valid ram areas) hid,1024,0x10000000,1G,0x00907000,0x31000 #Load complete FIT image to $ramdisk_addr_r tezi.itb:load 0x12100000 #Load script to $loadaddr and jump to it boot-sdp.scr:load 0x12000000,jump 0x12000000

Am I missing something, Thanks, Vincent

I have tested this method and it works, thanks.
Do you plan to usptream this method?
Or I can also put your patch as part of my series that adds SDP support for imx6qsabresd if you prefer.
Let me do a separate, I guess it could be controversial...
