Dear c6x: I have a question about XBUS of 6202. I use XBUS as asynchronous I/O. From the peripherals refrerence Guide I know i must use DMA to access the XBUS. But I can not access it. When i set the DMA destenation address as 0x80000000, it work well. But when i c

Any help with the following problem will be greatly appreciated. Our c6202 chip is Silicon revision 1.2. Question: We are trying to boot the DSP via the XBUS. We are using a Motorola 8260 CPU as the host, and a 6202 DSP as the slave. Our XBUS interface is setup to run i

We are having trouble waking up the 6203 DSP from an XBUS boot process. We can see that the code has been loaded correctly through the XBUS, but asserting DSP_INT doesn't appear to wake the DSP up. We know the code is OK because it runs if it's loaded through an emulator with Code Co

Hello everyone, I would like to know if the Xbus I/O port and the host port can be used together in a single system. To access the I/O port, the dsp would have to request the bus. But there is no HOLD and HOLDA timing information in the datasheet for synchronous FIFO access. So

We connect a POWERPC to C6202's expansion bus. So we choose the XBUS boot mode for C6202. But when we finished initializing the C6202's external memory configuration registers -- EMIF CE0 space control through the XBUS interface, the CE0 is not active for refresh SDRAM. And the same

Hi, I'm looking for a way to get the contents of the log buffer filled by LOG_printf in a host processor. Please, anyone knows a way to do this? I think that it would be a kind of library that contains functions to read the log buffer from DSP via, for example, XBUS port.
