Problems with uploading MIOS studio

[jjonas]

Hi,

I’ve been trying to get the core module working, but things have not gone according to plan. The problems started when I first tried installing MIOS onto the PIC (which I bought from Mike). I’m on Linux (Ubuntu 10.04) and I’m using a USB-MIDI cable with the upload.

When the power is switched on and I start the MIOS studio, the MIDI IN window displays:

Scanning for MIDI Inputs…

[1] Midi Through Port-0

[2] USB MIDI Interface MIDI 1 (*)

MIDI Monitor ready.

[2747.429] f0 00 00 7e 40 00 0f 00 00 f7

[2747.432] f0 00 00 7e 40 00 0e 03 32 f7

[2747.674] f0 00 00 7e 40 00 0e 03 32 f7

[2747.902] f0 00 00 7e 40 00 0e 03 32 f7

…and the window below displays:

No response from MIOS8 or MIOS32 core!

Check MIDI IN/OUT connections

and Device ID!

After this begins a steady flow of this:

[2750.219] f0 00 00 7e 40 00 01 f7

When I press ‘Query’, I might get the message:

Operating System: MIOS8

Board: MBHP_CORE or similar

Core Family: PIC18F

Bootloader is up & running!

So I start uploading the file mios_v1_9g_pic18f4685.hex. What I get is:

mios_v1_9g_pic18f4685.hex contains 12830 bytes (52 blocks).

Range 0x00000000-0x00002fff (12288 bytes) - MIOS8 area

Range 0x00003000-0x000033ff (1024 bytes) - PIC Flash

Range 0x00007c00-0x00007fff (1024 bytes) - PIC Flash

WARNING: no response from core

Please reboot the core (e.g. turning off/on power)!

Waiting for upload request…

Received upload request!

MIOS8 Bootloader Mode cannot be entered - try again?

This is where it ends most of the time, though sometimes the upload apparently succeeds. But if I keep pressing the ‘Query’ button (with device ID always 0), I sometimes get “Bootloader is up & running”, sometimes “Application is up & running”, sometimes “No response from MIOS8 or MIOS32 core!”

This seems to be happening randomly. When the upload fails (as it does most of the time), the message always turns into the following, no matter what it said before:

No response from MIOS8 or MIOS32 core!

Check MIDI IN/OUT connections

and Device ID!

And the MIDI IN window message changes into:

[221.399] f0 00 00 7e 40 00 0f 00 00 f7

[221.400] f0 00 00 7e 40 00 0e 03 32 f7

[223.583] f0 00 00 7e 40 00 0e 06 01 f7

After these three lines the message changes back into:

[352.193] f0 00 00 7e 40 00 01 f7

Here’s a sample of what is the MIDI OUT window after an upload attempt has failed, and the whole sequence ends with “No response from MIOS8 or MIOS32 core!”:

[983.768] f0 00 00 7e 32 00 00 01 f7

[983.768] f0 00 00 7e 40 00 0d 02 00 00 00 00 00 00 01 00 00 00 00 f7

(Personally I don’t understand anything of these numerical messages).

I’ve used two kinds of USB-MIDI cables, one is Roland’s UM-1G which, I later found, apparently has a bug with transmitting sysex messages:

http://forum.cakewalk.com/tm.aspx?m=1852997&high=sysex&settheme=Blue%20Cake

The message is from October 2009, and I haven’t found any follow-up on this. I tried another cable, a cheap generic one, based on a hint in this thread:

http://discourse.midibox.org/t/topic/14690

..where the problems seemed somewhat like mine, even though I’ve never gotten error messages like “Upload aborted due to error #3: Checksum mismatch”, “Upload aborted due to error #11: MIDI IN Overrun Error”, or “Upload aborted due to error #1: Less bytes than expected have been received”.

I’ve run all the tests I’ve found on the website (but it could be I’ve missed some) on the core and the connection, the voltage tests at http://www.ucapps.de/mbhp_core.html (naturally) and under the headline ‘MIDI Interface Troubleshooting Guide’. As far as I can tell, LEDs flicker, light up etc as they should. I didn’t make any notes on the tests, just went them through one by one, so I can’t refer to anything else at the moment, but I can run them again if someone has ideas on any particular test(s).

At some point I managed to upload the program to test whether the core is communicating with the SID correctly, the one with different notes on the MIOS studio virtual keyboard assigning voltages to various pins of the SID. Those seemed to be working.

Is there a way to test whether the PIC is broken? Even though I don’t work with microcontrollers at my job (I work with 230/400VAC), I do have stuff like STK500 and Elnec Smartprog2 at my disposal, if for example there are further ways to test stuff with these. Any ideas? I can also send pics if that is helpful.

Hi,

what do you think of the following? I finally got an LCD and connected it to the core, and when I switch it on (with only the PSU, the core and the LCD), the LCD displays the following:

1. ########################

2. MIOS V1.9g

© 2009 T. Klose

3. MIDIbox SID V2.0RC37

Launching CS

4. EInt^12PInt Ld Chn. 1

1***^12Lead Patch

So it looks like something has indeed been uploaded. Seems like it’s the MIOS there and the setup_6581.hex too, or what? Can you confirm this?

[T.K]

Due to the strange LCD output messages it seems that your installation is corrupted…

I never got the MIDI upload properly working on my own (old) Linux Laptop, therefore I can’t really help you.

Do you have access to a PC or Mac? (e.g. try it out with the computer of a friend)

Best Regards, Thorsten.

Hi,

which part of the LCD output is strange, and what should it look like (with just the core and one SID module)? I’ve attached images of the LCD output from yesterday for just in case.

Today at work I uploaded MIOS and setup_6581.hex onto the PIC on a Windows desktop computer, it seemed to work ok. I.e., there was no messages like “no response from core” before the upload began, pressing ‘Query’ returned consistently “Application up & running” etc.

Later at home I attached a bankstick module to it, which was duly formatted. The fourth message on the LCD has changed a bit, but to me it doesn’t look like a substantial change (I could be wrong of course). I’d be interested to know what the messages should look like. I will provide a picture tomorrow of the “new” fourth message if that’s helpful.. right now I don’t have access to a camera.

[jjonas]

Having now installed most of the buttons and pots, I think the core is working fine (with two SIDs and 3 banksticks). I’m able to navigate the menus, make and edit sounds etc. The start screen still displays “¹²” instead of “|”, but who cares..

The problem seems to have been with the GNU/Linux based MIOS upload (I had MIOS Studio running on WINE), because now that I’ve uploaded the MIOS and the SID hex on a Windows computer, the MIOS on my GNU/Linux laptop seems to be communicating with the core just fine (no error messages, virtual keyboard can be used to make sounds etc).

I uploaded the MIOS with the cheap generic USB-MIDI cable instead of Roland’s UM-1G, so I don’t know whether in addition to GNU/Linux the cable might also have been an issue. I wouldn’t like to try uploading with it just to check it out, because if it’s working, why fix it Maybe I’ll try that with the next core and report back after that (I’ll also post pictures of my über-cool case when I have it ready

I’ve heard stories about the UM-1G having weird problems. I have a MOTU Fastlane and an E-mu Xmidi 2x2. Both of them work very well with Linux.

hello,

 

I am running into a similar problem. I have put bootloader on an STM32F4, the green led turns on as it should.

I Start MIOS Studio and select the IN (1) and OUT (2) port of the MIDI interface. 

 

But i get a “No response From mios8 or mios32 core!”

 

Thanks in advance for your help

What MIDI interface are you using? I got similar problems with Audigy 2 ZS internal MIDI interface (with Midibox - no response at all; but with other devices it was working well, for example, with Roland SC and Yamaha MU series), semi-working Emu 2x2, but excellent results on FastTrack Ultra and ESI Juli@

I run GNU/Linux and have no problems with a variety of midi equipment.  Including a Roland UM-1X.  Sounds to me that it’s the UM-1G and/or the cheap generic interface that is likely the culprit.  Did you checksum the downloaded firmware before flashing?  Maybe you had a bad download?

 

Cheers,

 

Arkay.

hello, I bought a new board(still STM32F4) and the problem was fixed. I think it is a HW problem.

 

I don’t know for you esher
