Hi, We are trying to get the VC5402 DSK up and running with the AIC10EVM Codec daughterboard but are having a number of problems as detailed below. I would be grateful if anyone else, perhaps someone who has already worked through these problems, could lend a little insight into what is going wrong.. 1. It's hard to get the DSK board (without the AIC10) to reset. It can take a dozen attempts - unplugging, replugging, pressing the button etc. 2. We have been trying to run the DSK and Codec board. The demo C codec packages available from TI compiled and started up Ok. We were running AIC10Main with the following results: InitC5402 executes OK InitAIC10 starts and gets as far as label 'IdentStart' with A register containing FFFFFFFFFFh. Immediately before label 'FSCycle1' A register changes to 0000004021h In 'IfRxDY0' : A register changes to 0 at statement: 'BC IfRxRDY0,AEQ and loops back to the top of the subroutine. Each time through the loop Bit 2 is not set in the A register so the AND test fails. This loops for ever. This happens whether or not the Codec board is plugged in 3. We are using the following jumper settings on the AIC10EVM W1 =1-2 W2 = 1-2 W3 = 1-2 W4,W5 = 2-3 W6,W7 = 2-3 W8 open W9,W10 = 2-3 W11 = 2-3 W12 = 1-2 W13 = 1-2-3 W14 = 2-3 W15 = 1-2-3 W16,W17 = 2-3 W18,W19 = 1-2 W20 = 1-2-3 W21 = 1-2 W22 = 2-3 W35 - W38 = 1-2 W39,W40 = 1-2 W60 = 1-2 W61 = 2-3 W62 = 1-2 These settings are based on our understanding of the TI Publication SLWU003D Jan 2001: 'EVM User Guide' According to Table 2.5: the W6 and W7 settings shown above should connect to the DSP power and W18, W19 settings should connect 5V to DVDB and 5V to AVDB In fact the measured voltage on W18 1-2 was 3.2V and pin 3 was at 5.2 (NOT AS DOCUMENTED in TABLE 2.5) W19, as expected, 1-2 was 5.2V, and pin 3 was 3.2 On checking AVDD across C51 we found 5.2V (as expected) 4. When the AIC10 board is powered from the DSK board should DVDB be 5V or 3.3V or does it not matter? Best Regards, Kevin Howson Kane Computing Ltd |

Hi. I am experiencing the same problem as Kevin -- InitAIC10 routine will loop infinitely at IfRxRDY0. My jumper setting is slightly different from Kevin's :- W12 open -- disable DAA feature W14 1-2 -- use DSK's CLKOUT W18 2-3 -- to DVDB 5.0V W19 1-2 -- to AVDB 5.0V W35,36 open -- disable DAA feature W61 2-3 -- to DVDD1 3.3V Note:- Beside the supplies from DSK, my setup does not have any external power supplies(5V,12V) Appreciate greatly if anyone can offer insight to the above problem. Thanks & regards, Doreen P.S. Jean, did you encounter the above problem when you try the tone generation with AIC10EVM? --- In c54x@y..., "Kevin Howson" <kevin@k...> wrote: > Hi, > > We are trying to get the VC5402 DSK up and running with the AIC10EVM Codec > daughterboard but are having a number of problems as detailed below.
