I'm being asked to use the Ethernet-based Trek-ICE in place of my current -based Summit-ICE. My target is the Quad-SHARC 14060 (which has four ADSP-21060s). While I had some success with the Summit-ICE, the target did 'hang' occasionally indicating JTAG loss of sync, sometimes freezing the

Hi everybody, I am building the project with SHARC 21061 processor. I defined PMCO in the LDF file looks like this: ... ... ... seg_pmco { TYPE(PM RAM) START(0x00020098) END(0x00021fff) WIDTH(48) } ... ... ... The compiler/linker give me the error like " [Error li2007] Out of memory in memory segment "seg_pmco". While processing the input section "seg_pmco"

Hi all, I'm trying to implement a glueless RS232 interface to SPORT0 on my=20 21065L. My code is based on the ee-191 engineer to engineer=20 note, "Implementing a Glueless UART Using The SHARC=AE DSP SPORTs ". = =20 I've tied the RFS0 and DR0A pins together. The problem is that the=20 SPORT will occasionally lock up while receiving data from a PC over=20 the RS232 interface. I have t...

Dear all, I am using a SHARC dsp (ADSP21020) with 1 MB X 40 bit external data memory. I would like to use the complete 40bit memory to store and retrive the data. I had used assembly and C and set the MODE1 (bit 16) to configure the dsp for extended precision. However, it is using only upper 32 bits for any variables (int , long int, float, long double ). If i assign any register or va...

Hi, We have used T2PC TigerSharc Quad Processor DSP Card from Bittware. The card operation is really bizare like for following reasons 1. Processor and memory interface halts 2. PCI bus mastering fails 3. Data transfer from PCI BUS to PC RAM is shamelessly slow 4. Inter processor communication through LinkPort hangs can anyone guide me of good DSP Card of Tiger Sharc TS201S proc...

Hi everyone, I am using Apex-ICE emulator for on board emulation. I am using Visual DSP ++ SHARC IDE. My program is supposed to response IRQ0, and do the interrupt service correspondingly. I am wondering how can I set the breakpoint for the IRQ0 during the emulation. I know how to set breakpoint for simulation, but emulation is based on the hardware inte

I am facing problem in accessing the PCI memory location .The PLX 9656 registers are memory mapped into DSP memory location(starting from 0x02800000h) in which 0x02800000h indicates PCI DEVICE and VENDOR ID register(32 bit) which is read only. But when I am accessing that location I am getting some junk value . These are the things I did: I have done some DSP system configuration like ...
