Very odd that i2c_init gets called twice without a problem (once from Flash very early on) and once later before the POST tests run without a problem but then on the 3rd go (when called from i2c_probe) it hangs up!! Think I'd better check its being put into Master mode otherwise it won't do anything until it sees a clock presumably... -- Robin Gilks Senior Design Engineer Phone: (+64)(3) 357 1569 Tait Electronics Fax : (+64)(3) 359 4632 PO Box 1645 Christchurch Email : robin.gilks at tait.co.nz New Zealand
