i enable  Remove Filter  but it not find my com port. but i plug in 157c-dk2, cubeide will find it. so i dont know what cant find my com port.:face_with_tears_of_joy:

my pc can find com7. i can use com7 debug uboot and kernel. but cudeide v1.8 cant connect it.i can use the com7 for debug in putty, even if i close putty cude cant connect it.

my board is make for myself ,157d's debug uart connect CH340. sorry i not use discovery board. but it not work in cubeide v1.8 under win10. but now i can find but it cannot connect. i can use mobaxtrem connect com7 and debug.

i turn off vm but it also cant find any serial:dizzy_face: . but cubeide v1.4 is work in win10.

i have two version hw. ver.1 can use poweroff to close, but ver.2 can't both have same power support. ver.2 use poweroff and it will be go into bor_rst and reset the board.
