大家好
我用DVRRDK编译DVRRDK_04.00.00.03/ti_tools/syslink/syslink_2_20_02_20/examples/archive/TI816X_linux_elf/ex02_messageq例子,也生成了HOST DSP VPSS和VIDEO端的可执行文件,但在用fw_load.out加载时,内核崩溃,错误如下:
Attached to slave procId 2.
BUG: Your driver calls ioremap() on system memory. This leads
to architecturally unpredictable behaviour on ARMv6+, and ioremap()
will fail in the next kernel release. Please fix your driver.

VPSS VIDEO和DSP都报如上类似错误。
之前用fw_load.out加载编码应用没有问题,请问该怎么解决?十分感谢
