AW: [microblaze-uclinux] FSL

["Raul Camaras" <raul.camaras@xxxxxxxxxxxxxxxxxxx>]

Hello,
Thank you for your answer Stephane.
Next problem:
An application in Microblaze writing and reading from the FSL works.
It uses:

asm volatile ("nput %0, rfsl" "0" :: "d" (data_to_local_link[k]));

to write, and 

asm volatile ("nget %0, rfsl" "1" : "=d" (data_back_local_link[r]));

to read.

Under uClinux I try to use your example code, but the read call blocks
any time!
Did I forget some call to ioctl??
What can be the reason?
Thanks a lot.
Regards,
Raul Camaras

Hi Raul,

If you are on version 2.4, you can use the driver FSLFIFO made by Mr.
Williams. FSL driver are not yet available on version 2.6.

Here is an exemple assuming a request/response component on the FSL link
1 :

{
filerw = open("/dev/fslfifo1", O_RDWR);

res = write(filerw, &dataout[], dimout);

res = read(filerw, &datain[], dimin);
close(fichier);
}


Regards,

Stephane Rousseau
