Hello Albert, Thank you very much for your reply. I've checked the datasheet but I see no reference to base address registers for the mcBSP. mcBSP: http://www.ti.com/litv/pdf/sprugj6c OMAPL138: http://www.ti.com/lit/gpn/omap-l138 thanks again, Ran _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
