Hello,
Our team has recently used The i. MX 8M Mini Quad is designed with LPDDR4 and eMMC5.1. When we tried to download the program to EMMC using UUU, we encountered a problem, and after executing the download command, it stopped at the following interface, and no matter how long we waited, there was no change.
D:\Tools\uuu>uuu -b emmc_all flash.bin rootfs.sdcard
uuu (Universal Update Utility) for nxp imx chips -- libuuu_1.5.141-0-gde317f5
Success 0 Failure 0
1:33 1/ 1 [=================100%=================] SDP: boot -f flash.bin -scanlimited 0x800000
After using the uuu -lsusb command, I get the following result
D:\Tools\uuu>uuu -lsusb
uuu (Universal Update Utility) for nxp imx chips -- libuuu_1.5.141-0-gde317f5

==================================================
1:33 MX8MM SDP: 0x1FC9 0x0134 0x0101
What is the reason for this?
After executing the download command, the information output from uart2

Because the UART4 interface was not used when the hardware was originally designed, it is not possible to obtain information from the UART4 at present.
