BIT Linux parallel port issue

We'll look into adding the /dev/parportX entries to the test configuration list for selection as well.

Hi Tim,
This build works good. I can burnin with our new PCIE-to-LPT device.
I had some question, The BIT seems to get /dev/lp[x] io address
and direct write data and read status from IO ports. It's ok on legacy
& PCI devices. But if the device is implements with USB-to-LPT
(e.g., http://www.asix.com.tw/products.php?...4;109&PLine=74 ), the BIT will failed.
IMO, Could you survey to change raw access from IO port to /dev/parport[x] access? (e.g., http://yyao.ca/projects/ParallelPortLinux/). It's more portable and widely support for a lot device.
Thanks

Could you please launch BurnInTest with the command line parameter -d, reproduce the crash and send us a copy of the debug.log file that is created.
Hi Tim,
I had uploaded the log to GoogleDriver, Please use the following link.
https://drive.google.com/file/d/0B8v...ew?usp=sharing
The IO address of this device is using D062h (53346) with SPP mode.
D062h + 0: data
D062h + 1: status
D062h + 2: control
I can test for this if you need try with debug version BIT.
Thanks

BIT Linux parallel port issue
Hello,
We are developing a new IC about parallel port function.
We can read/write via /dev/lp0, but when we want to try loopback with BIT in Linux 3.3 build1001 . It'll crash and add log in dmesg with following
traps: bit_gui_x32[2526] general protection ip:807d2f7 sp:a92ec040 error:0 in bit_gui_x32[8048000+222000]

Also could you provide me the paralle port self test flow??
