Dear NXP team
I'm porting windows 10 IoT Enterprise to my custom board (i.MX8M plus),as described in i.MX_Win10_User's_Guide.pdf.
Question 1:
When I download the firmware.bin to emmc through uuu , it doesn't show [done](log as attachment download-firmware.png ), but it can boot and run winPE normally in sdcard(not contain firmware.bin). it seem download is success. I want to know why download success but not show [done] and Success 1 Failure 0.
Question 2:
Win10 IoT for i.MX8M plus EVK default display is LVDS to HDMI converter supported? Because my custom board is just HDMI output only , I want to know how and where can I change to HDMI display directly?
Best Regards
zhi

Hello @liuzhi ,
To 1st question - in case of any issues, you can update to the latest release version (1.4.193)
To 2nd question - yes, LVDS (or MIPI) converters are supported for i.MX8M Plus board. About HDMI output, there is no possibility to change output to HDMI because of missing driver. This feature will be available in future (approximately in 2 months).
Regards,
Michal

Hi Bio
Thanks for your support !
Question 1 is ok now;
Question 2 I try set "CONFIG_IMX_PERSIST_INIT=y" in my defconfig as your comment, still no HDMI out put. HDMI configuration and drivers are not set up in the kernel? I can't found the dts and kernel in Windows 10 Iot Enterprise BSP.
Best Regards!
