用azure提供的buildroot-BF60X.tar.bz2编译出来的uImage,在WL-BF609开发板上运行起来后就直接崩溃了。经过跟azure的工程师交流,应该是DSP的MMC复用了Eth1的某些脚,导致内核中MMC相关模块不能使用,所以uImage运行后就崩溃了。
对uClinux的Kernel作出以下配置后,uImage可以成功运行:
1. Power management options --->
[ ] Allow Wake-Up from PE12(ETH1_PHYINT, PUSH BUTTON)
2. Networking support --->
< > Can bus subsystem support --->
3. Device Drivers --->
[ ] HID Devices --->
< > MMC/SD/SDIO card support --->
Input device support --->
Miscellaneous devices--->
< > Blackfin rotary support
