Default console debug port was set in UART1 for mother board, but our customer IMX6 board was setting for UART3.
The console shows random unstable since turn UART1 to UART3 as follow:
root@sabresd_6dq:/ # UV
;kdlsrequest_suspend_state: wakeup (3->0) at 26127490005 (2015-01-27 02:54:39.635235336 UTC)
eth0: Freescale FEC PHY driver [Generic PHY] (mii_bus:phy_addr=1:04, irq=-1)
ADDRCONF(NETDEV_UP): eth0: link is not ready
ehci_fsl_bus_resume begins, DR
I have no idea to fix this issue, modify code as follow:
CONFIG_CMDLINE="noinitrd console=ttymxc2,115200 root=/dev/mtdblock2 rw rootfstype=jffs2 ip=off
static void __init mx6_sabresd_timer_init(void)
mx6_clocks_init(32768, 24000000, 0, 0);
- uart_clk = clk_get_sys("imx-uart.0", NULL);
- early_console_setup(UART1_BASE_ADDR, uart_clk);
+ uart_clk = clk_get_sys("imx-uart.2", NULL);
+ early_console_setup(UART3_BASE_ADDR, uart_clk);
this way is work for ubuntu BSP, so I don't know why android OS has this problem.
Please kindly teach me how to fix it!
Solved! Go to Solution.
Hi Public Account,
I am seeing these coming out from UART 3. Have you resolved your problem. I5ts very much appreciated if your could give me some hint
I would need to know where these came from and how to disable them . The baud rate is 115.2kbps. These looks to me like some command sent out from some driver
Thanks a bunc
