SPL hangs on a beagleboard during the serial initialization (line 40 of drivers/serial/ns16550.c). The reason is the non-empty shift register of TX (transmit FIFO is empty). To avoid the hangup include/configs/omap3_beagle.h has to be changed like in include/configs/igep00x0.h:
diff --git a/include/configs/omap3_beagle.h b/include/configs/omap3_beagle.h index 59255c4..63cd30b 100644 --- a/include/configs/omap3_beagle.h +++ b/include/configs/omap3_beagle.h @@ -81,6 +81,9 @@ #define CONFIG_SYS_NS16550_REG_SIZE (-4) #define CONFIG_SYS_NS16550_CLK V_NS16550_CLK +/* define to avoid U-Boot to hang while waiting for TEMT */ +#define CONFIG_SYS_NS16550_BROKEN_TEMT + /* * select serial console configuration */ Best regards, Manfred Huber _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
