What is the maximum speed of loading firmware through USBO2 with mfgtools on Windows?
I tested imx_usb_loader on Linux, and average loading speed was around 3.34 (Mb/s). I expected that it would be way faster than that. I tested MfgTool2.exe on Windows as well, but in VirtualBox and it was even slower - it could be because of the virtual machine though.
-----------------------------------------------------------------------
loading in mfgtool2:
<UCL>
<CFG>
<STATE name="BootStrap" dev="MX6UL" vid="15A2" pid="007D"/>
</CFG>
<LIST name="NAND Flash" desc="Choose NAND as media">
<CMD state="BootStrap" type="load" file="firmware/core-image-base-ccimx6ul.rootfs.ubifs" address="0x82000000"
loadSection="OTH" setSection="OTH" HasFlashHeader="FALSE" ifdev="MX6UL">Loading Rootfs UBIFS partition to RAM.</CMD>
</LIST>
</UCL>
--------------------------------------------------------------------
loading in imx_usb_loader:
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
firmware/core-image-base-ccimx6uluvalue.rootfs.ubifs:load 0x82000000
----------------------------------------------------------------------------
Are there any ways to increase the speed?
Thank you
Hi Andrew
I am not aware of speed with using mfg tools,
in general i.MX6UL EVK with nxp linux may reach about 25MB/s,
however this depends on processor load. Probably using hub may increase speed.
Best regards
igor
