Clock Speed Problem? - Roy Closa - Nov 6 2:26:00 2002

Hello everybody!! I have tried to initialize my TMS320C542 in a 100-Mhz Pentium I and selftest.exe is successful. However, I tried to initialize other TMS320C542's (3 kits in all) in a Pentium II and Pentium III PC's the selftest.exe (under c:\dskplus) responded with: Attempting 8-bit Data I/O . . . . 8-bit Mode is Functional No response from HINT interrupt signal. * * * * TEST FAILED * * * * I have tried the change the I/O configurations among Normal, EPP, ECP and EPP+ECP but to no avail. Is it really so that TMS320C5xx and TMS320C54xx DSP kits can run only on Pentium I platform? or is there a way to overcome this problem. I hope somebody in the group can answer this problem. Thank you!! |

Mabuhay! Roy, Selftest polls HINT to check dsp-to-pc interrupt. The poll duration could be too short in a Pentium II or III. Try increasing the duration by modifying HINT(duration) in line 190 of selftest.cpp (\dskplus\source) and recompile. Hope this helps.
