sprintf Posted February 4 Report Share Posted February 4 (edited) I suddenly have a Hard Fault 0x00018fc2 when powercycling and booting NG via USB Power / USB Data Connection. If the bootloader jumper is connected i can use the USB Connection to upload the bootloader . but after uploading NG again and rebooting , it wont boot back up after power cycling the USB Connection. The App will boot properly with external power and detached USB cabel. this suddenly occured i use a self powered usb hub . i tried disconnecting all attachments ( sdcard , scs ,etc .. ) but that does not change the behaviour. I also recompiled the hex and tried again , but no luck. does someone have a guess ? Edited February 4 by sprintf Quote Link to comment Share on other sites More sharing options...
