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...

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 -- Stefan > > Am I missing something, > Thanks, > Vincent > > 2017-09-01 22:09 GMT+02:00 Stefan Agner <ste...@agner.ch>: >> >> >> On September 1, 2017 12:25:44 PM PDT, Fabio Estevam <feste...@gmail.com> >> wrote: >>>On Fri, Sep 1, 2017 at 3:54 PM, Fabio Estevam <feste...@gmail.com> >>>wrote: >>> >>>> 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... >> >> -- >> Stefan >> -- >> Sent from my Android device with K-9 Mail.
