stopped booting from usb

MIDIbox NG
1

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 ?

hmm, i would first jumper all J5A/B/C - if they are open… so you have no noise from the ADCs… I know USB has nothing to do with ADCs, but that i would do first (  because that happend often when it not booted up)

A virgin  NG1.037? or somekind modified? (like the font thingi?)

post what you have in “mios32_config.h”

 

else i dont know, mostly i get  hardfault when writing negtativ values intos unsigned integer variables (aka use s16 instead of u16 variables), or doing mess with custom freertos tasks… i am really no expert for NG… you could post the code here (zip) and i can try if it does the same, have a stm or lpc here to test..

i thought it was a loose solder joint .

actually its not

4

it wont let me upload the file .

[mios32_config.h](< base_url >/applications/core/interface/file/attachment.php?id=15921&key=93e9a657e7a3e3996d8ed694de43bce6)

[project.hex](< base_url >/applications/core/interface/file/attachment.php?id=15922&key=ace7e7c137a70db13d6bcf7c492bf6ea)

LPC or STM?

8

ok, cant say what the display says (since it there is no) but the board led is blinking rapid. and mios studio does not recognize the board.

 

i tested it on the LPC-Core, plugged into my laptop

when i plug the usb-cable to a wall-5V adapter, its not  blinking.

 

so yes - this is a software thing, not a hardware.

 

about mios-config… there is a lot activated… do you use all the things in there? (#define MIOS32_SRIO_NUM_SR 32    and so on…)

9

sorry , i forgot to write its LPC. 

strange.

how its possible that suddenly it happened . even with a freshly compiled one ?

10

i used the ngc to deactivate srios . i only use 4 at the moment.

the display says HARD FAULT and (meanwhile) changing hex codes.

 

11

cant say, may a other can help,

but from where to you have that NG Version, because on http://www.ucapps.de/mios32_download.html

i see only 1.036! (i searched, and wanted to look if this also happend to a virgin ng…)

12

this version is what comes out when you compile ng from the actual github trunk .

i successfully used it for maybe 2 weeks now.

then suddenly it broke .

and i cant even use it after i compiled it again from src .

??

 

13

could you ,please try to compile the ng from the github trunk and see if its working ?

so this means , its better to edit the mios-config , before i compile ,right ?

15

i jumpered J27 in order to come into bootload-mode… (in order to upload new code…)

then downloadet the actual bootloader, and made sure that i used the correct LPC1769 since mine is a 1769

then dowloaded the actual github zip from https://github.com/midibox/mios32

set the environment variables to lpc… restardet

built the NG-code from the downloadet github… (“make clean”, then “make”)

uploadet the build project.hex

removed the J27 jumper (then mios made a softreset

mios writes:
 

no response from CLCD.... (off course nothing connected) Init DHCP PHY initialized SD Card not found

no problem up to this point

 

but after reconnecting the USB-Cable (aka hard-reset) it goes into HARDFAULT —aka blinking rapid

 

so it is confirmed the actual NG-Firmware was not tested for a LPC-Core (maybe someone made changes, but tested it only on STM32?

this is writing while building (for those who looking into this tread, and having a glue…)

hmmm has to do with UART

because when i add follwing line to mios_config.h

#define MIOS32\_DONT\_USE\_UART

the board is working normal,

i dont know what UART in this sense does? (USB-midibports??? Din-Midiports?) i dont know

this is all i can do, the rest has to be done who knows this application

18

Thank you for all your effort .

I was really getting frustrated .

_

this is really sad news , since i was actually working with this release . now i cant compile any more.

 

UART here , has either something to do with Ethernet / RS-232 Interface or a Serial Connection ?

i will check if i can use the release properly without UART .

19

hello again .

i also have hard faults with 1.036 now .

but only every 2nd or third time i reconnect the usb cabel .

im wondering if maybe something got seriously damaged .

how warm will the lpc get usually ?

the mcu is getting warm . i can still touch it but im wondering why it is warm at all with such small duties .

this is the normal official release from the download page .

is there a way to identify the hard fault adress ?

i measured mine (with nothing connect then the usb-cable: 40°C

measured with a infrared-“gun”
