Again with problem "Couldn't find the DFU device: [1EAF:0003]"

Hi leaflabs,

I think my problem is clear:
Reflashed the maple_boot.bin built from "maple-bootloader.git", no user code in flash.

My situation is:
While using IDE, it came a message "Couldn't find the DFU device: [1EAF:0003]".
While using libmaple in command line, typein "dfu-util -a1 -d 1EAF:0003 -D build/maple.bin -R", it came a message "No DFU capable USB device found".
While typein "dfu-util -l", there would be the situation same as unplugging maple usb cable.

The most strange thing is that there was no usb device listed out (typed in "lsusb") for corresponding maple board while the borad running looks correct(fast flash then slower).

I've tried methods mentioned in forum, program it directly without recognizing serial device.

And checked the docs for 0.0.12
https://github.com/leaflabs/leaflabs-docs/commit/20567605e2cc6a0414177b87efc7ab9b495898e2

Still doesn't work.
So, I have to turn to you excellent guys :P

My environment:
Board: maple r5
Host OS: Fedora 15 & Ubuntu 11.04 & Windows XP

Ps: Before I reflash the bootloader, it worked well on each environment.

Thanks,
Librae

I think in the bootloader, maple will talk to host pc, so usb device cannot be nothing with the board.
There should list a usb device called as leaf:0004 or something.

According to above, the problem seems to be on the hardware...

But I've measured the usb cable with the chip, nothing seems wrong - -!

Any ideas?

OMG!
Fix it.
It's about the hardware.
I heat the miniusb and those two resistances around it use soldering iron and everything is ok now.

wow...

sorry you were having trouble. but you say you are all set now? was the USB port just not 100% on and so heating it improved the joint?

Hi poslathian,

Many thanks for your attention.
Yes, I heat it and it is all ok now.

I am considering that nobody would come because it is a so low-class problem caused by myself.
I might hit it on somewhere...

Maple board is very nice actually :P
Keep going on!

Hey poslathian,

Here comes another question about the USB.
I am trying to use a non-maple board for now.

Should it be listed out as a USB device on host PC after downloading & running maple bootloader?

Is there any hardware related issues?
Because I don't have a BUT and a BOOT0 pull down connection, just a jumper to choose 1 or 0 for BOOT0.
Can I make it recongnized by PC USB with or without some rework with hardware?

Many Thanks.

I am considering that maple bootloader do "setupUSB()" while initializing, so it can be recongnized when even running bootloader only.
Right?

have you ported the bootloader to work on your new board? does it have the same USB DISC pin as maple?

if the answer to either of those questions is yes, then things should work, and the board should come up as a DFU device. if the answer to both of those questions is no, then you'll need to port the bootloader to your board.

Thanks mbolivar,
I did port the bootloader to my board and the usb pins are identical (stm32f103rbt6, there are only those two pins for usb).
So, I think it should work, but bot.
I download bootloader to the chip, then reset. While the led is flashing fast, I still didn't see any usb device by 'lsusb'.
Maybe I need a check and a rework on the borad hardware?

the USB DISC pin is neither USBDP nor USBDM. it's a normal GPIO not used by the USB peripheral on the stm32. we use it to let the host know we're there. see e.g. setupUSB() in the native-boot branch:

https://github.com/leaflabs/maple-bootloader/blob/native-boot/usb.c#L36

also see setupUSB() (heh) in usb.c of libmaple v0.0.12:

https://github.com/leaflabs/libmaple/blob/v0.0.12/libmaple/usb/usb.c#L102

OH I See. I'll try that when I'm back home.
Thanks a lot, mbolivar! :P
