Brief Summary: The DSP/BIOS HWI module is not saving and restoring the 'RB' register with interrupts disabled. This can cause the application to crash in random fashion. The only workaround is to disable interrupts around any 'RPTB' loops or update to DSP/BIOS 5.33.03.
主要bug描述:DSP/BIOS在使用HWi模块时,取消中断不能保存和存储RB寄存器。
解决方法:升级DSP/BIOS版本到5.33.03或者用RPTB循环
