Hello, I'm trying to run upgrade MidiBoxLC v1.6e on a PIC18F4620 with MIOS v1.9g. But after many ours of struggling, searching the forum for answers and testing some settings, I didn't find a way to get the glcd running. If I compile and upload the hex file, it looks like as if the ram for the fonts was overwritten (there is only rubbish at glcd). MIOS Studio says: Reading setup_midibox_unit0.hex Trying to contact the core... setup_midibox_unit0.hex contains 18860 bytes (75 blocks). Range 0x00003000-0x00007aff (19200 bytes) - PIC Flash Upload of 19200 bytes completed after 11.37s (1.65 kb/s) So, it shows that area 07cfc-07fff (where MIOS font is stored) is not affected. - I can upload app Mios example app lcd7/ks0108 and I get the correct welcome screen. So this works. - I can upload my compiled MidiBoxLC and pushing buttons or touching faders are producing midi events I can see in MIOS Studio. Things I've done and/or tried: - copied app_lcd.asm /.ins/.lcd from projekt lcd7/ks0108 into MidiboxLC folder modules/app_lcd/dummy/ - In Makefile.org: set PIC to 18F4620 - I also tried to edit file p18f4620.lkr in MIOS_Base/etc/lkr to split memory page as shown in http://www.midibox.org/dokuwiki/doku.php?id=using_pic18f4620 but this doesn't work for me. And now I need an idea which setting I am missing ... Thanks for any advice, Stefan
