Here it is its output: barebox:/ dump_clocks chip id: [2,882,1,01d] mpll: 600000000 Hz spll: 240000000 Hz arm: 400000000 Hz perclk1: 20000000 Hz perclk2: 40000000 Hz perclk3: 100000000 Hz perclk4: 40000000 Hz clkin26: 26000000 Hz ahb: 133333333 Hz ipg: 66666666 Hz barebox:/ This is what I get after the last configuration I tried: writel(0x00262C15, MPCTL0) writel(0x040C2403, SPCTL0) writel(0x33F30207, CSCR) /* Use DIV3 and AHBDIV=10 */ We have three different boards using iMX27L; on two of them Barebox with this setting runs properly, on the third we frequently see the system hanging (cyclic restarts). Note: I have the same results with: writel(0x33F30307, CSCR) /* Use DIV3 and AHBDIV=11 */ Best regards, I. _______________________________________________ barebox mailing list barebox@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/barebox
