Captain_Hastings Posted August 25, 2003 Report Posted August 25, 2003 I had a core with bootstrap 1.1b, mios 1.2, tc 1.1, ID = 0000000000000000, but i couldn't sysex it anymore...But if i send F0 00 00 7E 40 00 0F F7 i got F0 00 00 7E 40 00 0F 00 F7 back. Midi in and out seemed to work ok.My sysex setting are 4* 2048, delay 750 after F7.If i tried to overwrite the tc 1.1 app: nothing, no checksums, an automatic mios reboot, but the 1.1 app was still there.Upload MIOS 1.3 during first 2 secs of startup: nada.Now i burned a new pic with bootstrap 1.1b, id 0, and it just keeps sending F0 00 00 7E 40 00 01 F7 every 2 secs, even during upload of mios 1.3, and still no checksums...But it did work before, so... what to do? :'(I've read TK's bootloader pages over and over again but am i forgetting something important?

TK. Posted August 25, 2003 Report Posted August 25, 2003 I guess that the download fails due to a feedback loop: Ensure that the datastream from the MIDI In port is not forwarded to the MIDI Out port in order to avoid a feedback loop! Deselect the Auto-switch in the lower left corner before selecting a MIDI In/Out port so that this connection will not be done automatically. Check the port mapping at the right side: the MIDI In port should not appear in the list!Best Regards, Thorsten.
Captain_Hastings Posted August 25, 2003 Author Report Posted August 25, 2003 Hi Thorsten, thanks for the reply!Checked it but i think i have the device setup right?
TK. Posted August 26, 2003 Report Posted August 26, 2003 Are you sure that this isn't a bug in the kx driver? You can test it in the following way: create a "physical" loopback with a MIDI cable (direct connection from MIDI Out to MIDI In), open the SysEx tool of MIDI-Ox, load the .syx file and start Send/Receive SysEx.If the number of received bytes doesn't match with the number of transmitted bytes, you've a problem...Best Regards, Thorsten.
Captain_Hastings Posted August 26, 2003 Author Report Posted August 26, 2003 Yikes!If the number of received bytes doesn't match with the number of transmitted bytes, you've a problem...Ok... i think that's bingo, if i send a sysex i receive 0 bytes back on the input port with a physical loopback.I'm gonna try with the lastest kx drivers tonight...
Captain_Hastings Posted August 26, 2003 Author Report Posted August 26, 2003 Yiehaa! :DUpdated the kx drivers and everything is ok!Many thanks for the help Thorsten! Now i can start on my first MIOS app ;DPictures of the box soon!cheers
