C6657串口工具显示



CCS V6.1

EVM6657L

mcsdk_2_01_02_06

串口工具:HyperTerminal和SecureCrt

1.按照read me文档将mcsdk中POST例程通过I2C下到EEPROM,bus address 0x50,重新上电前,将Boot Mode Dip Switch Settings拨到I2C POST boot模式,

I2C POST boot (off, off, on, off, on, on, on, on)

(on, on, on, on, on, on, on, on)

上电后串口工具无显示;重复多次均无显示;

2.然后再将mcsdk中POST例程通过I2C下到EEPROM,bus address 0x51,重新上电前,将Boot Mode Dip Switch Settings拨到I2C boot模式( 0x51

I2C boot (off, off, on, off, on, on, on, on)

(on, on, on, off, on, on, on, on)

上电后串口成功显示POST自检信息;

3.在此条件下,重新执行1中的0x50模式,上电后串口亦成功显示POST自检信息;

4.将IBL通过I2C下到EEPROM,bus address 0x51后,再执行1中的0x50模式,上电后串口工具再次无显示;

5.IBL NOR boot on image 0 (default)和IBL NAND boot on image 0上电后,串口工显示正常。

还请各位大神不吝赐教,谢谢!
