My Grinn liteboard uses i.MX6UL processor, and I am using Buildroot. I can get boot my board with my images through the use of a uSD card. But I want to use MFG Tool to transfer my images to my board so that I can boot my board without having to burn my images to a uSD card. I don't want to have to use the uSD card. As far as my research has shown, my board needs to be detected as a HID compliant device in order to do the transfer without uSD card using MFG Tool (and even if I follow tutorial Guide to flash iMX6 from Linux to use Linux to achieve what MFG Tool does). However, I have tried many ways to do so, but my board only shows up as a com port (COM3). There is no "HID conform, from producer defined Device" driver either for me to install so that my board shows up as HID compliant. I have already changed my boot mode to Serial Downloader mode, but I cannot figure out what is wrong.
Anybody face a similar issue? Am I missing some set up configuration? Or is there any way for me to transfer my OS image to my board directly to boot so I do not need a uSD card in order to boot? Can anyone point me in the right direction?
Edit: I have tried imx-3.14.38_6UL_ga_mfg-tools and the latest L4.1.15_2.0.0-ga_mfg-tools, both of which end up with MfgTool2.exe just opening up telling me No Device Connected. My Device Manager detects my board only as a COM port. I am using Windows 10, but I have tried Windows 7 on VirtualBox, which also shows No Device Connected when I run MfgTool2.exe. I cannot figure out what I am missing?? All I want is to be able to transfer my OS to the board without a uSD card.
