our carrie board usb function can work ok with KetPack 5.14 -35.6. I only use the usb as device no other otg/usb pd functions. the dtb file need to be modified ?
system config:
1>Carrie Board : No EEPROM(0x56)
2>Carrie Board: No MBEB PHY
modify:
1:修改p3701.conf.common
修改ODMDATA: ODMDATA=“gbe-uphy-config-0,hsstp-lane-map-3,hsio-uphy-config-0,nvhs-uphy-config-0”;
2》修改 flash size=0x00
USB2.0 -Port0 ----> USB Download Port
USB2.0 -Port1 ----> USB Tye A(标准USB接口)
Decompile the original dtb file under the module’s /boot/dtb into a dts file.
Make the necessary changes: only disable ucsi_ccg@8 and changing the USB 2 mode to host.
修改完设备树后,启动后USB不能识别,USB2.0的引脚是直接从ORIN引出的,请问可能是什么原因引起的? dmesg.txt (56.9 KB)
