请问如何将SYSBIOS中默认的2.5MHz修改为28377D最大频率200MHz?
mangui zhang:这个是不是在时钟硬件平台的输入频率呢 ?

Susan Yang:您可以看一下

1a. For 28x devices, SYS/BIOS installs a configurable Startup reset function called ti_catalog_c2800_init_Boot_init(), which is provided by XDCtools. Depending on your configuration of the ti.catalog.c2800.init.Boot module, this function performs the following actions:
Disables the watchdog timer
Configures the PLL
Sets the CPU frequency to the one you have configured
For eZdsp283xx boards only, configures the XINTF external memory interface
