Cerebral Infect

Sorry to ressurect an old topic, but that also solved the same problem on my MB-6582. The encoder was going up and down by steps of two. Yeah I have realized that I have put this project on hold for a too long time !!! Thanks to all for this support forum. It is useful, but I had to dig quite a bit to find an answer for that one ! :P

If that can help you, I had loads of problems to upload to the core. See my discussion between me and Wilba if it can help you.

Received mine today. :D Many thanks !

Look for the worst looking solder joint in the SID voice module. But have you tried both L and R chips ? If both doens`t work, it`s the core. It would help if you had the LCD working to see if the CORE is working correctly. Is your LCD connected like this : http://www.midibox.org/users/jim_henry/building_a_midibox_lcd_cable.pdf I remember you had problems with the LCD from chatting yesterday.

Pic to proove it did happen ! Have a good cold one too ! 100_1255.JPG 100_1255.JPG

Success ! I was able to load Sid R31 OS to the core using the core feedback option on BUT with "Wait for upload request" off. Whenever I putting the "Wait for upload" on, there was always an error a Packet 294. I then reformated the bankstick with the ensemble socket. The problematic stick was the original "ensemble" bankstick. So I've put it in socket A, reformatted it and placed the other in and everything works. Loaded the patchs and tadam, I could play the patch. Thanks Wilba for the help. Thanks Thanks Thanks, I was trying stuff but not really logically. As for infos to the others. My midi controller is an Edirol PCR-M1 and once I understood the twist around uploading the midibox OS, everything went well. On the other Hand, the Novation Remote SL was not good at all. Lots of missed packet send. Anybody else had bad experience with the Novation Remote SL ?

Okay, I made some progress. I've removed the bankstick. Made bunch of uploads to the Core. I was able to upload MIOS with "Wait for upload..." in manual mode. Then I was able to upload the SID OS to the core in manual mode, but without the "Wait for upload..." Channel 1 to 4 are working. I can play notes with the MIOS midi keyboard. I then put the bankstick on the unit. It is when the unit doesn`t work anymore. It boots at channel 16, I can flip thourgh the presets, but does make any sounds when playing the keyboard. On any channel. So I think it goes down the banksticks. Any Ideas ?

Hi, I removed the bank stick. Uploaded the Mios 1.9 for PIC18F4685. No problems. Then I tried to Upload the MB6582 Hexfile and I have the same error message on all cores at #294. It is just like yesterday. What is supposebly suppose to happen at 294 ? It stops ? I`ll tried tonight with a different midi interface.

Hi Wilba, What you proposed was exactly what I was doing. So I used shorter midi cables, unplugged the power supply for a while. Repluged everything in. Powered On and I was able to send the hex to the core BUT At packet 293 (or 294) an error message appeared "Received error code 0B: MIDI IN Overrun Error" and the hex file process started again. When I pressed stop, the Midibox LCD showed that the unit was formatting the memory banks. So I`ve uploaded the Hex file to the other cores, all 3 with the same error messages at packet send 294. I've then uploaded the SID preset patches with no problems to bank A. The new problem is that when the SID unit starts, it start at midi channel 16. I can switch through the programs and bank using midi messafe from my midi controllers. But it doens`t respond to midi notes. I hear the 4-5 notes when the Midibox boots, but after, I cannot make sound. Is no making sound related to the "upload error at packet 293-294" or the unit is stuck a channel 16 and the core respond only to channel 1 to 4 ?

Hi, I've pretty finished the Mainboard. I've tested the Sid with the testone program. I was able to upload the program to all four core. Now I am trying to upload the MB-6582 hex file and I have this following error : Sending block #1 00003000-000030FF Error: Received unexpected Upload Request Received error code 0B: MIDI IN Overrun Error Does anybody encountered something similar ? Does the bankstick chip being installed changes something ? Thanks !

Received the new replacement bridge rectifier by SmashTV. Desoldered the previous one. The desoldering pump was a life saver. Soldered a new one in. Turned on : no smell. Touched the bridge : no heat. Let time pass by : No pop corn effect. People on the forums were rigth, it was the bridge rectifier, not the PSU. I can resume construction of the unit. I can`t wait to test the SID I've receive from Wilba !!! Thanks everyone.

I think it's really the power supply failing. I found this interesting link for testing PSU. Mine shows 5.2V DC. Therfore I think I have a failing regulator. The hunt for a use C64 begins now. http://personalpages.tds.net/~rcarlsen/cbm/pstester.txt I'll keep you updated.

Hi, I'm building a MB-6582 from a kit of Smash TV. So this week I assembled all the sockets, headers, resistance (except R40 to R55), diodes, some capacitors, and the PSU section. Did my ground check and 5V check for continuity on the sockets. Then I put my Power supply. It's a Commodore 64 PSU. Checked the Pin on the PSU to validate if I had 5V DC and 9V AC, which I have. I assembled PSU Option A since I have 6582 chips. So I plugged in the PSU on the board and flicked the switch to on. Check the DC voltage : 5V ! good. Then check the 9-11V header and I had 13.2 Volt, witch is higher than anticipated. Checked the voltage at the SID Header and read a 9.00V at each of them. I was happy. Until I notice a little burn smell and look at the bridge rectified. A teenager during puberty could not have done better. The rectifier developped a little bulge and gets really hot. I checked my soldering underneath and it`s good. Has anything like thing happened to you ? Or my PSU is too "hot" ? See at the pic bridge.JPG bridge.JPG

Just made Paypal payment. I hope that everything`s in order then. Thanks !
