Question about the PipXtreme

[Wei Tang]

Hi all

    I have made the PipXtreme, and after download the bl_pipxtreme.bin by STLINK start address from 0x08000000, when I plug into the PC's USB want to download the fw_pipxtreme.tlfw by GCS, the PC displayed "UNKNOWN DEVICE", but the USBLED indicator on the PipXtreme blinking, seems the software is running.

My question is there something wrong with my operating steps,thanks

[Wei Tang]

and what does  bu_pipxtreme.tlfw and bu_pipxtreme.bin used for?

You need to upload the bootloader before use GCS. Do you have any programmer?

I have upload the bl_pipxtreme.bin use ST-link

[peabody124]

So I just compiled with this

make ef_pipxtreme

and then uploaded it with this command (serial port)

./tools/stm32flash/stm32flash -w build/ef_pipxtreme/ef_pipxtreme.bin -s 0x08000000 /dev/tty.usbserial-00001014B

and my pipx is flashing. http://imgur.com/KKKG1XA

Your board layout looks different than any I've seen before, so it might have some hardware bugs though.

I use the make ef_pipxtreme,and download the ef_pipxtreme.bin by ST-link,

and it seems a little good, the "heartbeat LED" looks good, frequency about 2Hz.

could you please give your ef_pipxtreme.bin,and let me have a try ,thanks

I am working with the WeiTang, and I debug the bl_pipxtreme code.  

the program looks like good because PIOS_USB_CableConnected() return true, and PIOS_USB_Init() is ok.

but the device name is "unknow device", so I think the bl_pipxtreme dosen't return the usb's device descriptor.  
can you tell me , how can I debug the problem, thanks a lot. 

by the way the function PIOS_USBHOOK_GetDeviceDescriptor() can not been called. 

I am not familiar with the USB Protocol. I need your help. thanks.
