USB library problem

[ilferrari]

Hi all

I have written my own bootloader and firmware using HID_Enable/HID_Disable, HID_Read/HID_Write, and USB_Polling_Proc. Sometimes when it jumps from the Firmware to the Bootloader, Windows will lose sight of the HID device and there is no way to reconnect unless you remove and reattach the cable, then it will re-enumerate. Both the bootloader and firmware do the same thing after they start - HID_Enable, USB_Polling_Proc, then HID_Read/HID_Write. I have tried already calling HID_Disable before jumping.

Does anyone know a reliable method of jumping between the bootloader code and the firmware code using the above library functions.

I am using PIC32 at the moment, but I have had the same issue on PIC18

Hello,

I suggest using compiler bootloader example projects as a guide for you development.
Bootloader projects are located in: ..compiler\Examples\Other\USB HID Bootloader\

Best regards.

I will suggest you check your clocking. 48Mhz for full speed and 6Mhz for slow
