    We were in contact with James Murphy. His contact info is: SEGGER Microcontroller 106 Front Street Winchendon, MA 01475 T: 617.874.1255 F: 978.874.0599 E: james.murphy@segger.com http://shop-us.segger.com | http://www.segger.com We received the boxes the week of July 14, 2014, I believe. I downloaded and installed version 4.96h and tried to do an update. Screen captures are attached. Segger1 is a picture of the firmware update dialog box showing that the update failed. Segger 2 is the jLink Comm…

    We have a number of jLinks, version 8.0, serial numbers 58004877 and 58004879, that we recently got as a trade-in from some older boxes. I recently upgraded to IAR version 7.30.4 with Segger jLink drivers version 496g. When I try to use one of the jLink boxes, I get a box that asks if I want to upgrade the jLink firmware. If I say no, it tries to download the code but then I get an error that says "Communication timed out: Requested 6 bytes, received 0 bytes! Could not read speed info." If I say…

    I can successfuly run all of your Bulk interface tests on the Embedded Artists board with your supplied Windows executables.

    I am unable to build working test apps (e.g echo1.exe) for Bulk from the sources supplied. While they build and run, they do not 'see' any USB devices. Please advise.

  • Found it. Can't do a SVC call with interrupts disabled. The documentation says that the OS layer wants a couple of functions that disable and enable interrupts. This doesn't work with SafeRTOS. I used portENTER_CRITICAL and portEXIT_CRITICAL instead. This leaves interrupts enabled but ensures that task switching doesn't occur within the critical section.

  • We’re getting a hard fault on our LPC1788 processor when executing an SVC #3 instruction after trying to read a character from the USB port after enumerating in CDC mode. The hard fault has only the Forced bit set. The SVC exception has a priority of 0 (the highest), and the processor is not in an exception when the hard fault occurs. If enumeration is the only thing done, the firmware keeps running normally after the connection. But once an attempt is made to read a character from the USB port …

    I cannot rebuild the sample apps (e.g. echo1) because USBBULK.h is missing. Where can I find this?
