issues installing the Maple drivers

hi all

i may have missed the answer to this while searching hte forums but im having issues installing the drivers according to this: http://leaflabs.com/docs/maple-ide-install.html.
i can successfully install the dfu drivers, however after resetting the board my seems to stay in bootloader mode as the LED doesnt stop flashing - if this is the test program (blink code) then thats cool.

however windows never prompts me to install the usb drivers and as such the maple IDE doesnt even know the board is there.

any ideas what it could be? i have tried manual pointing the path to the directions but that didnt work.

im on a win XP machine trying to use Maple 0.011

any help or suggeatsions would be greatly appreciated

cheers

Hi Jase,

I just dealt with this yesterday, and hope I'm understanding your problem clearly.

Your IDE is not recognizing the USB serial port, right? The directions leave out the second step(took me a few days messing with it to figure out that was my problem).

Go through the same steps (Control Panel>System>Hardware Tab>Device Manager. For me, it showed a yellow question mark next to Maple 3, above the Ports(COM & LPT). click on it, driver tab, update driver, and when the wizard asks for you to search for drivers, direct it to MapleIDE\drivers\mapleDrv\serial (my ide is in MapleIDE, change it for your own directory structure).

If I understood your problem correctly, that should fix it, it worked for me :)

Cheers

did this fix your problem? Looks like a docs bug.

p.s. we've been playing with an installer which should take care of this in the future.

this is what the device manager looks like for me - http://i56.tinypic.com/au6opj.jpg - the Maple 003 shows up under LibUSB-Win32 devices. attempting to change the drivers for this doesnt work as it sees the dfu drivers as the best.

i might start from scratch installing the drivers again - if that doesnt work, i will use a jtag device to examine the STM32

i still havent got my USB drivers to install yet - if only got back to it in the past couple of days due to other tasks getting in the way.

is the code used for testing the blink code? because according to the instructions

1. Reset your Maple and allow it to exit the bootloader (wait for the slow blinking to stop). The Maple will next start running whatever program was uploaded to it last. (New Maples will start running the test program we upload to them before shipping them to you).
2. Once Maple is running some user code, Windows should prompt you for more drivers. Point windows to driver/mapleDrv/serial.

on my board the slow blinking doesnt stop - so i am wondering if it is successfully leaving hte bootloader

Have you tried uploading a blinky program to the device?

1) put the device in perpetual bootloader mode
2) check the tools->serial port menu to see what COMs are available (and make a mental note)
3) open blinky from the examples->digital->blink
hit upload

it should complain about the reset sequence, but then upload anyway (because youre in perpetual bootloader mode)

By the time the device is running the blinky sketch (should be a slow 1s period blink), you should definitely have the virtual com port (serial) port up. You can check the tools->serial port menu again, and check for a new com port (like COM4 or COM7). If there is a new one, you are all set - select it and youre done! If there is not, than window will either prompt you for a driver, or you can the uninstalled device in the control panel->devices menu.

i changed blinky to a 3 second period and it looks like i successfully uploaded the code as shown in the image: http://i55.tinypic.com/2q2ppjt.jpg - but the LED is flashing more than once a second and the com port isnt showing up in either device manager or in the maple IDE.

order a second maple and it works first time - so there maybe an issue with the first one i ordered. i'll look at the working one with the jtag and compare the code on both of them to see if there is any differences

Sorry to hear your first Maple was misbehaving. Please keep us posted on what you figure out with JTAG.

I just ran into what appears to be the same exact issue, while playing around with a the audio codec shield (I'm on Windows 7). The COM port no longer appears in device manager. Nothing appears in normal mode. If I put the Maple in continuous boot-loader mode, then it appears under libusb-win32 devices as "maple."

The biggest problem with maple on windows is that you have to install two drivers. One for DFU and one for serial. In both cases the device has to be present, which means you have to get the device into dfu mode to finish installing the drivers and you have to have it in the cdc-acm mode (or you have to load valid code in that mode) to get the other driver installed.

I tried to teach a class on using c with the maple and we spent the majority of it getting windows to cooperate.
Its just ugly, and with the $igned driver$ policies being added to 8 its going to get worse.

update: I tried to use the maple on another machine running Windows XP - same problem: I can get the maple into perpetual bootloader mode and install the DFU drivers (where it appears under "LibUSB-Wind32 Devices" as Maple 003, but on reset / out of perpetual bootloader, nothing is being picked up.

I'm not sure if reflashing the bootloader will help? I'm taking a gander at the instructions, but I'm not clear on how to physically wire it up using an Arduino (I don't have an FTDI breakout board):

If you do use an FTDI breakout board, first make sure your Maple is disconnected from an external power source, be it battery, USB, or barrel jack. Then, connect the FTDI board’s TX pin to Serial1‘s RX pin (labeled “RX1” on the silkscreen), FTDI RX to Serial1 TX (labeled “TX1”), FTDI ground to ground (labeled GND), and its 3.3V pin to Vin. On Maple Mini, you will also need to tie BOOT1 (pin 2) to ground.

Does this mean the Arduino's TX pin to Maple's (Serial1) RX pin? etc?

UPDATE: So yeah - I guess that's what my question above meant. I'm trying to go through an Arduino Uno: do I need to upload some sort of special sketch to it first? Otherwise, I'm getting this output error:
```
U:\My Documents\mapleboot>python.exe stm32loader.py -p 5 -evw maple_boot.bin
Traceback (most recent call last):
  File "stm32loader.py", line 473, in <module>
    cmd.open(conf['port'], conf['baud'])
  File "stm32loader.py", line 74, in open

al\serialwin32.py", line 53, in open
    raise SerialException("could not open port %s: %s" % (self.portstr, msg))
serial.serialutil.SerialException: could not open port 5: (2, 'CreateFile', 'The
 system cannot find the file specified.')
```
The Arduino is being recognized on its com port in device manager (COM5). When I ran the above code, I tried entering serial ports 0>6 (just to make sure it wasn't how its indexed in the script) and get the same error every time.

Update, I need to read directions more closely - needed to enter in COM5 (not just some index) when calling stm32loader.py

I now get the following error - not looking good:

U:\My Documents\mapleboot>python.exe stm32loader.py -p COM5 -evw maple_boot.bin
Reading data from maple_boot.bin
Can't init. Ensure BOOT0=1, BOOT1=0, and reset device
Traceback (most recent call last):
  File "stm32loader.py", line 486, in <module>
    bootversion = cmd.cmdGet()
  File "stm32loader.py", line 139, in cmdGet
    if self.cmdGeneric(0x00):
  File "stm32loader.py", line 136, in cmdGeneric
    return self._wait_for_ack(hex(cmd))
  File "stm32loader.py", line 87, in _wait_for_ack
    raise CmdException("No response to %s" % info)
__main__.CmdException: No response to 0x0

To clarify, I've made sure that the maple is in hardware serial bootloader mode. The Arduino is running whatever was running on it last - haven't done anything to it.

Update: Tested it on a friend's Macbook. No luck, the system wasn't picking up the maple in either regular/bootloader mode.
