Image Filterig Using Custom IP and DMA on ZedBaord

[@tyagiavinash045]

My log file is not receiving any data after sending the input image file in teraterm successfully. It was working fine when I tried with the software design of the image filtering but the above problem is occuring when I am trying the IP for image negative which is created earlier. I tried to check the ILA but the debug core is also not getting triggered after running from SDK.

@Vipin Kizheppatt. Thank you so much for these videos. Have you ever had a problem with the "send file" not working on Teraterm? Every time, I have to send it a second time for the log file to receive it. I have copied what you did exactly, except I am using Vitis 2021.1, not SDK.

@Ben Campion . my log file is not receiving the data at all even after I tried to send it multiple times. Any idea how to resolve it?

@Vipin Kizheppatt Thank you. Your teaching is very helpful to me. When I print the error code, it is "F" or "XST_INVALID_PARAM". Among the arguments of XAxiDma_SimpleTransfer, "imageSize" is replaced to 10000, so it works normally. As expected, only some of the images were inverted. What is the problem?
Please advise once more.
The Results is...
=================
&myDma= 30D8C4, (u32)&imageData[headerSize]=10C4C0,imageSize=40000
DMA1 initialization failed
F
The Code is ...
================
#define imageSize 512*512
#define headerSize 1080
#define fileSize imageSize+headerSize
.
.
int main(){
u8 *imageData;
u32 status;
.
.
//memory allocation of a sppace of file szie in DDR
imageData = malloc(sizeof(u8)*(fileSize));
.
.
//read data to DMA and then, DMA data to the IP core and Process
status = XAxiDma_SimpleTransfer(&myDma,(u32)&imageData[headerSize],imageSize,XAXIDMA_DEVICE_TO_DMA);
xil_printf("&myDma= %0x, (u32)&imageData[headerSize]=%0x,imageSize=%0x


", &myDma,(u32)&imageData[headerSize],imageSize);
if(status != XST_SUCCESS){
print("DMA1 initialization failed
");
xil_printf("%0x
", status);
return -1;
}
status = XAxiDma_SimpleTransfer(&myDma,(u32)&imageData[headerSize],imageSize,XAXIDMA_DMA_TO_DEVICE);
if(status != XST_SUCCESS){
print("DMA2 initialization failed

");
return -1;
}

There is more than 1 case where invalid param error can come. Can you do one thing, in the xaxidma.c file, in the XAxiDma_SimpleTransfer function put some debug print (like print("Case1") print("Case2)) etc. before return XST_INVALID_PARAM; lines? In that way can isolate the exact reason.
