Stephan_WE Posted March 25, 2013 Report Share Posted March 25, 2013 Hi, we just uploaded the midiboxng application the first time. In Bootloader Mode(J27) we can upload the Midibox NG Appliciation. After removing the jumper J27 we can send commands (help/system) and get a response. As soon as we reboot the device, no communication with the application is possible any more. We see "Midibox NG" in MIDI IN and MIDi OUT within Mios Studio. No response on query. What's wrong ? Best regards Stephan Quote Link to comment Share on other sites More sharing options...
John E. Finster Posted March 25, 2013 Report Share Posted March 25, 2013 You have to install the bootloader without the jumper J27. You can use jumper J27 as a failsave in case the bootloader crashes and you do not have access to it the usual way (without J27). Try removing Jumper J27 and upload the bootloader again. After that you can upload the midibox_ng application. Quote Link to comment Share on other sites More sharing options...
Stephan_WE Posted March 25, 2013 Author Report Share Posted March 25, 2013 Hi, we installed the bootloader via LPC-Link. We than connected via the usb connector on the midibox as described here http://www.ucapps.de/mios32_bootstrap_newbies.html and uploaded the midibox_ng application. I don't understand how we can change this. After reset, we see the "Midibox" IN and OUT Devices but get no response within the MIOS Terminal. I thought, that we have to install the bootloader only once. Quote Link to comment Share on other sites More sharing options...
ilmenator Posted March 25, 2013 Report Share Posted March 25, 2013 (edited) Which bootloader version are you using? Make sure it is the latest one (v1.012), otherwise the application may not run properly. Edited March 25, 2013 by ilmenator Quote Link to comment Share on other sites More sharing options...
Stephan_WE Posted March 25, 2013 Author Report Share Posted March 25, 2013 We downloaded the sw today. It ist v1.012. Quote Link to comment Share on other sites More sharing options...
John E. Finster Posted March 25, 2013 Report Share Posted March 25, 2013 (edited) Indeed you have to install the bootloader once via LPC Link (project.bin), but you can upload the bootloader any time after that via usb on the Core PCB (project.hex) if you want to change the lcd type for example. After the bootloader is installed the first time, you can upload an application via usb on the Core PCB, but you have to remove Jumper J27 for that. Edited March 25, 2013 by John E.

TK. Posted March 26, 2013 Report Share Posted March 26, 2013 Please keep the special installation instructions "Working under Windows?" into account: http://www.ucapps.de/midibox_ng_manual_in.html Best Regards, Thorsten. Quote Link to comment Share on other sites More sharing options...
Stephan_WE Posted March 27, 2013 Author Report Share Posted March 27, 2013 Thanks, it is working right now. We have to select the midi in and out ports multiple times and eventually the LPC is responding. So we have to look into the driver issue.
