Ok I have done that cross compiled it and stuffed it into my RAM Disk.

When I run tpcal it hands back seven parameters. With the MIPS code
those values
were placed into /etc/pointercal. Which mou_tp.c would read and use to
adjust the
values being returned from the touch screen device. (calibration occured
on the application side.)

I notice that the ts_ioctl supports seven commands. So do those seven
values represent (raw_max_x, raw_max_y, res_x, res_y, raw_min_x,
raw_min_y, xyswp)?

Not knowing what they are I do not know what to do with them. Nor can I
tell if the values I am getting are reasonable.
tpcal results: (-273605, -633, 174383829, -700, 278166, -4003337, 65536)


Should I send them to ts_ioctl cmd's 3-12?

Thanks,
Scott
