I am trying to boot i.MX6 UL Custom Board using usb_loader.

 

Given below is the configuration I use:

 

mx6_qsb

#hid/bulk,[old_header,]max packet size, dcd_addr, {ram start, ram size}(repeat valid ram areas)
#hid,1024,0x910000,0x10000000,1G,0x00900000,0x40000  << original value

hid,1024,0x910000,0x08000000,512M,0x00900000,0x40000 << modified for UL Custom Board with 512MB memory

u-boot-sd-2016.03-r0.imx:dcd,plug
zImage--4.1.15-r0-imx6ulcustbrd-20170322082522.bin:load 0x80800000
xyz-image-imx6ulcustbrd.rootfs.cpio.gz.u-boot:load 0x83800000
zImage--4.1.15-r0-imx6ulcustbrd-20170322082522.dtb:load 0x83000000
u-boot-sd-2016.03-r0.imx:clear_dcd,jump header

Are the updated values for following are correct?

dcd_addr, {ram start, ram size}(repeat valid ram areas)

Please explain more about these variables.
