I have a problem with the digital audio interface, I am using follow hardware: eval board EVK2 with the UC864 interface.
problem: The digital audio port is configured as Master (Slave is not connected) and I can only measure the clock signal. (see attachment: UC864_DAI_1-CLK_2-RX_3-TX_4-FS.png)
question: why i can not measure the PCM_SYN & PCM_TX signal? is this a fundamental problem or am I doing something wrong?
The problem is as follows reproducibly: > EVK2 with UC864 Interface is used > serial connection is used (115200baud, 8data, none parity, 1 stop bit, Hardware Flow Control aktiviert), Software TeraTerm V4.73 (SVN# 4845) > connection test at OK at+cpin? +CPIN: READY OK

Thanks a lot for your help
Hi Sebastian.
Thanks for contacting the forum.
All DVI pins except CLK share teh GPIO function so you need to select alternate function for them so:
AT#GPIO=17,X,2 // enables SYNC function
AT#GPIO=18,X,2 // enables RX function
AT#GPIO=10,x,2 //enables TX function
So all should be working….
it works … (party)
thanks

Hi Luca
Twoquestions on theGE864–GPShardware manualsaysthat theballK7 (DVIRX), ballD7 (DVICLK)andH5ball(DVIWAO) areI /Obut sinceI can readif I want touse asGPIOandas DVI AT #GPIO=?, 0What isare the addresses ofthese threeI /O?or isan errorin the manual
Best Regards

Hi Giovanny,
are your question related to Sabastiamn one? since this post was related to UC864 product and you are talking about GE864 GPS.

Hi Luca
Two questions on the GE864–GPS hardware manual says that the ball K7 (DVI RX), ball D7 (DVI CLK) and H5 ball (DVI WAO) are I / O but since I can read if I want to use as GPIO and as DVI
AT # GPIO =?, 0 What is are the addresses of these three I / O? or is an error in the manual
