TI技术支持工程师你好！
我公司现在 用TI 提供的LCDK开发板文件试小批量生产，SDK也是TI网站上下载的，linux 3.3.0，u-boot也是此SDK提供的，现在发现有些板能正常启动linux，有些板子则停止在“Uncompressing Linux... done, booting the kernel. ”不动了。

在u-boot下，用查看内存，经过跟踪调试发现是
static __init void omapl138_lcdk_init(void)
{
int ret;
davinci_serial_init(&omapl138_lcdk_uart_config);
/*
* shut down uart 0 and 1; they are not used on this board and
* accessing them causes endless "too much work in irq53" messages
* with arago fs
*/
__raw_writel(0, IO_ADDRESS(DA8XX_UART1_BASE) + 0x30);
__raw_writel(0, IO_ADDRESS(DA8XX_UART0_BASE) + 0x30);
omapl138_lcdk_config_emac();
ret = da850_register_edma(da850_edma_rsv);
pr_info("INIT: da850_register_edma\n");
if (ret)
pr_warning("%s: EDMA registration failed: %d\n",
__func__, ret);
omapl138_lcdk_mmc_init();
pr_info("INIT: omapl138_lcdk_mmc_init\n");
omapl138_lcdk_usb_init();
pr_info("INIT: omapl138_lcdk_usb_init\n");
ret = da8xx_register_watchdog();
pr_info("INIT: da8xx_register_watchdog\n");
if (ret)
pr_warning("omapl138_lcdk_init: "
"watchdog registration failed: %d\n",
ret);
ret = da8xx_register_rtc();
pr_info("INIT: da850_register_rtc\n");
......
}
是停止在 da8xx_register_rtc() 此函数不动了，屏蔽此函数则可以了，为什么会这样的呢？
