Lamouette Posted April 23, 2012 Report Share Posted April 23, 2012 Hi there ! I finnished to build my LCP17 Board, and i prepare the LCP1769 to mount it on the LCP17 board. So i flashed the 1769 and cut it in 2 parts : When i connect the 2 parts and connect them via usb to the computer, the led light and fade 3 time, stop, and goes on. i have to check another time but normally it´s that. am i OK ? Problem : afetr that, i put the half card, on the LCP17 Board, but when i connect the USB, all the led (LCP176 and ethernet port led light 1 time, and i have nothing more working ? What i should do to debug it ? Power supply problem ? i really don´t know.... HELP :) Quote Link to comment Share on other sites More sharing options...
TK. Posted April 23, 2012 Report Share Posted April 23, 2012 Hi, if the LED flashes 3 times it means that the MIOS32 bootloader is up&running! :) (after the 3rd flash it will start the application - you can disable this via "fastboot option") It means that you can now upload an application via MIOS Studio - you don't need the LPC Link anymore! afetr that, i put the half card, on the LCP17 Board, but when i connect the USB, all the led (LCP176 and ethernet port led light 1 time, and i have nothing more working ? Probably you connected the LPC Link port with the MBHP_CORE_LPC17 module. This option is only intended if an external JTAG debugger should be connected via J3. If you still want to use LPC Link for whatever reason (but I don't see a need for this, as the application has to be uploaded via MIOS Studio, not via LPC Link!), you either have to solder the LPC Link socket the other way around: Best Regards, Thorsten.

Lamouette Posted April 24, 2012 Author Report Share Posted April 24, 2012 (edited) Ok, so i think i have a problem : - I mount the half-lcp1769 on the LCP Board - But : !!! If i connect the usb plug with Jumper J15_s in 5V, the led on the LCP1769 light 1 time and stop and nothing happens (J26 not connected to the lcp1769) If i connect the usb plug with Jumper J15_s in 3.3V, the same thing happens (J26 not connected to the lcp1769) If i remove the Jumper J15_s, the LCP1769 is in continious flashing (On off with fade -> on off with fade -> ... There is no jumper in J1;J2;J18 if i let the usb pluged, the IC6 is cold (a bit warm) and IC7 is really hot. Thx to help me ! Bye Edit : Up Edited April 25, 2012 by Lamouette Quote Link to comment Share on other sites More sharing options...
TK. Posted April 25, 2012 Report Share Posted April 25, 2012 Seems to be related to a short circuit in the LCD circuit, this especially explains the higher LF33 temperature -> see also this schematic to locate the affected components which are supplied by the middle pin of J15_S: http://www.ucapps.de/mbhp/mbhp_core_lpc17.pdf This is the location where you have to search for bad solder joints and/or bridging junctions.

Lamouette Posted April 26, 2012 Author Report Share Posted April 26, 2012 ok thx TK, i´ll try that ! Quote Link to comment Share on other sites More sharing options...
Lamouette Posted May 6, 2012 Author Report Share Posted May 6, 2012 (edited) Ok, i verified the pcb, but for me all looks like nice... now : When a connect the USB Plug : with jumper on 3.3V : i light (ethernet fix, and the led of the lcp1769 flash (on off on off on off...) with jumper on 5v : same thing... Each time the IC6 and IC7 seems cold or not too hot. i add link for the photo of my PCB, maybe something will appears obvious for you. Maybe i burned a pic cause i worked with a pull over. i can try to change them. Thx ! Edited May 6, 2012 by Lamouette Quote Link to comment Share on other sites More sharing options...
Lamouette Posted May 10, 2012 Author Report Share Posted May 10, 2012 (edited) ok, i tried to upload the .hex and it seems work as well. Mios studio write : [9913.662] [MIOS32_MIDI_SYSEX_Cmd_Debug] command handler not implemented by application so i think it's ok. What i have to do now ? how i can know if everything is working fine ?
