各位大侠,我现在用IMX。6的处理器,UBOOT启动时,打印信息到
MMC: FSL_USDHC: 0,FSL_USDHC: 1,FSL_USDHC: 2,FSL_USDHC: 3 有时就停止打印信息,
有时能起来,但是打印信息MMC: FSL_USDHC: 0,FSL_USDHC: 1,FSL_USDHC: 2,FSL_USDHC: 3
*** Warning - bad CRC or MMC, using default environment
In: serial
Out: serial
Err: serial
i2c: I2C2 SDA is low, start i2c recovery...
I2C2 Recovery failed, I2C1 SDA still low!!!
Net: got MAC address from IIM: 00:00:00:00:00:00
FEC0 [PRIME]
Hit any key to stop autoboot: 0
这是什么原因产生的? |
