Am5728 board does not recognize dlp devices?
The source code path of dlp is: www.ti.com/.../dlplcr4500evm (DLPLCR4500GUI-3.0.1-windows-installer.exe). The source code of QT is migrated to arm 5728. In fact, no changes have been made, but the compiler is replaced by arm gcc. The compiled executor runs on the arm5728 board, and am5728 does not recognize it. Am5728 uses development board of Chuanglong in guanzhou .
According to the information printed by am5728, we can know that the dlp module has been identified on the am5728, track the migrated qt project, and find that the calling hid_open () returns an error, so the phenomenon of hanging can be seen on the board of am5728.
QT project migration to ubuntu can run, indicating that there should be no problem with the qt project itself, from which it can be inferred that it should be the problem of usb library or udev library on the single board. There are libusb1.0 libraries and libudev libraries found on the 5728 single board. Do you have version restrictions on these two libraries? do you have to install libfox-1.6? In the instructions for the qt project, it is found that what is this for build HIDAPI?
Thank you!
