It seems it's not like that. > Anyway, thank you, I solved the problem already. Your message is probably delayed a couple of days since you are a new member and the forum is moderated. How did you solve the problem between CSL versions? What did you change?

I am having a problem with a program running and having interrupts get disabled. The hardware I'm using has a sequence of thigns happening that are fired off by timer interrupts and then by EDMA completion interrupts, and then I also have a UART handler runnign related to interrupts. Intermittently the processor stops sending all interrupts, and when I halt the processor in the debugger, ...

Hi guys, I am having some trouble of missing some bits of data when I sent out data between two TI DSP processors using McBSP of one(DSP-I which is TMS 6711) to the UART of another(DSP-II which is TMS 6701). I have a setup in which I recieve digital data(somewhat sine wave-ish) though a serial port of a DSP-I, which is filtered there and also

Hi, this may be board related problem but i was clue less on this. needed help. I am using 6711, code running internally. CE0 space is used for SDRAM, CE1 for Flash, CE2 for SRAM and CE3 with a 3to8 decoder for interfacing i/o. In i/o devices like UART, ADC are interfaced parallally, it inclueds some other leds and digital sensing inputs. And th

Hello all I'm a grad student at UT, Arlington and have been working with the C6711 DSK for the past year. I have been reading up on McBSP based communication. I need some help with the EDMA part. I have read spra633a.pdf which talks about configuring the McBSP as a UART.

Hi, I'm working with the 6711 DSK and using DSP/BIOS. I'm trying to write code that receives on the McBSP (configured as a UART), uses EDMA to transfer that data into the receive buffer, quickly processes the receive buffer in a HWI, and then triggers a SWI for further processi
