Hi everyone,
My name is Landice. I'm a student in Taiwan. I'm new to OpenRISC1200 and wishbone, but I need a SoC platform to finish my graduate degree, so I found the work minsoc.
I start to read the documents, code yesterday. When I tried to make the adv_debug_sys/Software I get some error message as following

cable_ft2232.o: In function `my_ftdi_set_event_char':
/home/landice/System_Design/examples/minsoc/minsoc/rtl/verilog/adv_debug_sys/Software/adv_jtag_bridge/cable_ft2232.c:148: undefined reference to `ftdi_set_event_char'
cable_ft2232.o: In function `my_ftdi_usb_purge_tx_buffer':
/home/landice/System_Design/examples/minsoc/minsoc/rtl/verilog/adv_debug_sys/Software/adv_jtag_bridge/cable_ft2232.c:118: undefined reference to `ftdi_usb_purge_tx_buffer'
cable_ft2232.o: In function `my_ftdi_usb_purge_rx_buffer':
/home/landice/System_Design/examples/minsoc/minsoc/rtl/verilog/adv_debug_sys/Software/adv_jtag_bridge/cable_ft2232.c:113: undefined reference to `ftdi_usb_purge_rx_buffer'
collect2: ld returned 1 exit status
make: *** [adv_jtag_bridge] Error 1

I went to /usr/include/ftdi.h to look for these definition but I couldn't find them.
I use the latest libftdi-dev library install by 'apt-get install libftdi-dev' under Ubuntu.

This problem may seem stupid, but I'm new to linux and open source SW/HW.
Thanks a lot.

Hi Landice,

You will probably get a better response if you ask this question on the OpenRISC forum. That is where the minsoc/ORPSoC experts tend to be.

Best wishes

Jeremy

Hi Landice,

Jeremy was right, I don't generally check this forum but I have just noticed your post (late but now). There are some things you should check:

first: did you edit the Makefile? It is set to cygwin by default, you have to change it to linux.

second: are you sure you installed libftdi, try it again to be sure, "sudo apt-get install libftdi-dev", I'm using ubuntu-9.10, used 9.04 and also have installed it on debian 5 (lenny), it always worked after installing it. Also libusb-dev was necessary (sudo apt-get install libusb-dev). In /usr/include/ftdi.h I actually found the missing function from your error (int ftdi_set_event_char(struct ftdi_context *ftdi, unsigned char eventch , unsigned char enable);).

third: if your cable isn't a ftdi based cable you can easily switch it off and compile adv_jtag_bridge without it. To do it just edit Makefile changing SUPPORT_FTDI_CABLES=true to false.

I hope that helps you to get it running. On which board are you planing to use, install minsoc?

Best regards,
Raul

I'd have responded sooner, but I've been travelling for a week...

The errors you posted are link errors. Are these all the errors, or are there others? I would also expect compiler warnings (if the functions don't appear in the header).

If there's a problem with the libftdi installation, then I'd also expect more errors: one undefined reference for each call to a libftdi function.

I suppose it's also possible that the libftdi interface has changed since the cable driver was written...but it would have to be very recent...
