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!
