[ts-7000] Re: Lincan module: TS-7260 / 2.6.21-ts : insmod throws segmentation fault

["gajans.garage" <>]

Dear Gonzalo and Mariela, 

Thank you for your quick responses. 

First of all I have only one jumper at 4. (Address = 0x150, IRQ = 5/6)

Gonzalo I tried the #define TSXXX_BASE_IO 0x11E00000. 

but still getting the same segmentation errror :(.

I noticed one thing. The manual says 0x11E00150 is the 'physical'
address. but the Kernel is complaining about trying to allocate
'virtual memory' at 0x11E00150. please shed me some light on this issue. 

Thank you 
Gajan
