Hi Steven,

thank you for your answer.

But this original code seems to be ok.

static int rs_brg_map[] = {
	6,	/* BRG7 for SMC1 */
	7,	/* BRG8 for SMC2 */
	0,	/* BRG1 for SCC1 */
	1,	/* BRG2 for SCC2 */
	2,	/* BRG3 for SCC3 */
};


	/* Wire BRG7 to SMC1 and BRG8 to SMC2 */
	immap->im_cpmux.cmx_smr = 0x11;

Best regards
Marco
