Hello;
In our design we want to inferface an ADC with my Beaglebone and then send the information through UART. We are using McASP (McASP0) configured in interrupt mode (no DMA), where after every adquisition of McASP data, data is processed and once in a few adquisitions, data is sent through UART1. We are using Starterware.
We want to acquire data and process it it a high frequency, and here is where our problem appears. As the data processing time is quite high (around 2.5 useconds), we have activated the Neon and VFP coprocessors (both in our projects and in the system, utils, platform and devices projects). In a simple desing where only the data processing functions are included, we can check easily (with some GPIO toggle) that the data processing time lasts around 300 nseconds. However, if we activate the Neon and VFP coprocessors in the McASP release app, the McASP does not happens and the ISR does not activate.
Is there any conflict (Starterware, processors, ARM...) between the Neon and VFP coprocessors and the McASP? Where is the error? Is not possible to combine Neon and VFP coprocessors with McASP?
Thanks a lot.
