Simulating Serial Ports in VDSP++2.0 for SHARC

Hi,

Would someone explainme why and how to correct the following: Using the ADSP-2116x simulator for ADSP-21160, if I set the SPEN bit on SRCTL1 the simulator shows a dialog where stands "Port doesn't exist or isn't opened".

I set for example like this:
R0 = 0x00000000;
dm(SRCTL1) = R0;
R0 = 0x000065F1;
dm(SRCTL1) = R0;

And when stepping after tha last instruction I get the message.

How can I simulate usage of this serial port?

Thanks!

Thanks folks. Fortunately I got it solved. Even got it working properly for chained DMA acquisition, ideal for block processing (which is what I really need).

Kindest regards,

Hi
i had tried the simulation of serial port transmission in
visual dsp++ 2.0 simulator environment for the 21065L. it works
properly. my configuration is not as same as ur configuration. for
my specific application i configured TX1_A and RX1_A for
communication at multichannel mode. The vdsp2.0 tool is itself have a
problem for DMA simulation for 21065L (pls check :

253D205%2526level2%253D%25252D1%2526level3%253D%25252D1%2C00.html
Anomaly no. : 9268
but for my case i first tried the absolute address of receive and
transmit buffers are written to the index registers of corresponding
DMA channels. but on simulation the first data recieved frm RX1_A or
transmitted through TX1_A is not properly written to their respective
location.(receive buffer for RX1_A and output file for TX1_A). but
when i change the address to absolute address - 0x8000(starting
address of 21065L) , the steaming simulation is working properly. i
also encountered the same problem "*** Port doesn't exist or isn't
opened ***" , when i am not properly configuring the streaming
parameter.
(The data acquisition routine is for a AC97 complaint codec. 8-32bit
word array for total 256bit frame)
below is my register and TCB configuration for simulation from C-
routine
// Set up tansmit DMA tcb
xmit_tcb[7] = (int)tx_buff - 0x8000; // internal dma
address
xmit_tcb[6] = 1; // internal modifier
xmit_tcb[5] = 5; // internal count
xmit_tcb[4] = (((int)&xmit_tcb[7])&0x0001ffff)|0x00020000;
// set the pci bit on transmit block chain pointer
xmit_tcb[3] = 0; xmit_tcb[2] = 0; xmit_tcb[1] = 0;
xmit_tcb[0] = 0;
// Set up receive DMA tcb
rcv_tcb[7] = (int)rx_buff - 0x8000;// internal dma address
rcv_tcb[6] = 1; // internal modifier
rcv_tcb[5] = 3; // internal count
rcv_tcb[4] = (((int)&rcv_tcb[7])&0x0001ffff); // receive
block chain pointer
rcv_tcb[3] = 0; rcv_tcb[2] = 0; rcv_tcb[1] = 0; rcv_tcb[0] =
0;

*((int *)MTCS1) =0x001f; // 5 channels enabled // transmit on
0,1,2,3,4
*((int *)MRCS1) = 0x0007; //3 channels enabled //
receive on 0,1,2
*((int *)MTCCS1) = 0; // no companding on transmit
*((int *)MRCCS1) = 0; // no companding on receive
*((int *)RDIV1) = 0x00FF0001;
*((int *)TDIV1) = 0x00FF0001;
*((int *)STCTL1) = 0x001c11f2; // slen = 31, sden & schen enabled
*((int *)SRCTL1) = 0x078c45f2;

*((int*)CPT1A) = xmit_tcb[4]; // DMA transfer starts
*((int*)CPR1A) = rcv_tcb[4]; // DMA reception starts

i think this may help u.
