Regarding UART/GPIO

2007-04-18 Thread ketan deshpande
Hi all, I have a doubt: If the ARM processor's ROM bootloader(RBL) doesn't read a valid UBL, it is going to always default to the UART Boot Mode. It happens on the DVEVM, we checked. But then, the UART0 pins are MUXED with GPIO35 and 36. On power-up, it is set to GPIO. It can be set by

Yes SOUND_MIXER_VOLUME is supported and would work also - but up to the limit set by the gain. The DaVinci OSS driver uses the V3 of the OSS API. There are some pointers as to which mixer ioctl to use depending on what you want to do at http://www.4front-tech.com/pguide/ Best regards, Loc

Real-time performance measurements

Hi all, I was wondering if anyone has done any measurements on the real-time peformance of the GIT or the montavista kernel? By peformance I mean interrupt and task latency. We are wondering if Linux running on TI DaVinci in a sufficiently loaded system would always be be able to have
