Just to give a feedback from Ver 0.5. Here it worked without any issues and without any additional todos. The only thing i have done to prevent electrical problems was to remove the 5V wire from the small USB connector first before uploading the new bootloader from the PC. Uploding works errorfree and instantly after this i updated from the big USB to the most recent firmware image. I tried this with 2 different USB sticks. One older 512 MB noname stick (giveaway gift) and a 2G Transcend stick. Both work fine with Ver. 0.5

Hi Andreas,
Still I can't load the firmware. I checked the big USB port, power is OK (5V), all connections checked OK. Also checked the processor clock, running OK. It looiks like here is no reaction on pressing the Band- button, so I did check that. What puzzles me is that I measure no voltage over the open contacts of this button, when I do so with the Band+ button I measure 3.3 Volts ! So I checked if the contact is really open and it is. I also checked the trace from the button to PB0 of the processor, it's OK ! The processor is brand new out of the box from Mouser. Soldering looks perfect under a loup lamp (nice shiny joints, no shorts).
Am I right there should be 3.3V over the open Band- button, like over the Band+ button (PB2) ??

Hallo Uwe und alle anderen, die die Möglichkeit vermissen, die aktuelle Software direkt (also ohne USB-Stick) auf den mcHF zu laden
Hierzu ist kein "mchf-manager" oder andere Spezialsoftware erforderlich. Es reicht aus, dfu-util zu installieren. Die entsprechende Windows-Variante (wie auch die für Linux- und Mac OS X Anwender) findet sich auf der Seite
http://dfu-util.sourceforge.net/
und die eigentlichen Installationsdateien weiter auf
http://dfu-util.sourceforge.net/releases/
Hier den entsprechenden Link zum Download anklicken, die aktuelle Version ist dfu-util-0.9-win64.zip. Bei der Installation eventuell bitte den Hinweis zur (impliziten?) Nutzung von libusb 1.0 auf der Seite http://dfu-util.sourceforge.net/ beachten(Verweis auf https://github.com/libusb/libusb/wiki/Windows#How_to_use_libusb_on_Windows).
Nach Beendigung der Installation (und der ggf. nötigen Durchführung von System-Anpassungen) ist dann vorzugehen, wie bereits unter "UI-Board und Linux" ausführlich beschrieben wurde, um die Software vom PC auf den mcHF zu laden.
Vielleicht findet sich jemand der Windows-Anhänger, der die Installation und die spezielle Handhabung für den mcHF Schritt für Schritt erläutert (bei mir läuft nur Linux, so dass ich hier nur theoretisch agieren kann …)

Hallo Andreas,
ne ne Andreas ich vermisse gar nichts! Alles bestens so wie es ist. Ich hatte mich nur in die Diskussion eingemischt und wohl "zu weit aus dem Fenster gelehnt". USB Stick, großer Port alles perfekt!

Hello Jos,
bootloader version 1.2.0 ? May be is it not the right version of the bootloader?
BL: 1.0 --> with modification, the "small" USB connector
BL: 2.0.0 --> the "big" USB connector

Hi Andreas and Winfred,
Thanks for the replies
The bootloader I'm using is the one found under "Latest release version 1.2" and I guess it is bootloader version 2.0, a bit confusing is'nt it ?
Well there should be 3.3V over the opened Band- button as I supposed. There isn't, so there is but one conclusion possible : The new processor doesn't pull-up PB0, which is vy strange for a brand new one. Luckyly I ordered 2 of them, I will exchange it and hope for the best (hope the PCB will withstand all that mistreatmnt).
Best 73 Jos

Hi Andreas,
I exchanged the processor (STM32F427VIT6) this morning and you feel it coming : Makes no difference !
Installing the bootloader went flawlessly: "Upload succesfull". Jumper J6 has been removed. When I press the power button, button Band+ goes high (3.3V), Button Band- remains low. I checked the Band- button for a short, it is open. I checked for continueaty from Band- button to PB0 (pin35) of the processor : trace is 0 Ohms
Conclusion : It has no sense to press Band- button for loadng the frmware, for it is low already.
Question: What makes PB0 go high, there is no firmware loaded yet. Should it be high by default of the processor, is it done by the bootloader or what else?
That the problem is caused by processor failure now looks unbeleavable to me.
I'm confused, remember, all went well with a 32F407VGT6 and the same USB stick in the DFU USB connector. I am even thinking of going back to the old processor but I don't like to (another attack at the PCB).

OK, the bootloader. I took the bootloader from the website under "Latest version 1.2.0" twice, correct ? Any other ideas ? Jos

If you mean with "website" Andreas' github site: https://github.com/df8oe/mchf-github/releases than you are perfectly fine under 1.2.0. There its the bootloader.dfu Image. After installation with Dfuse the mcHF shows a "Bootloader 2.0.0" in the power on screen.

@ Peter Yes, that is the one, I am using that bootloader.dfu file from there.
@ Andreas I will do some more tsting, maybe the old bootloader and the memorystick on the mini USB connector. Will keep you informed. Nice weather here, 30 degrees C, no good for HAM radio
