Part Number: AM3359
Other Parts Discussed in Thread: PROFIBUS

Hi,

Let me talk about PROFIBUS using AM335x.

PROFIBUS datasheet mentions pin assign for PROFIBUS.

C:\ti\PRU-ICSS-Profibus_Slave_01.00.01.01\docs

・pr1_pru1_gpoY(Y=0..20)

It means PRU1's pin is used

But PR1_PRU0_PRU_R30_5(MCASP0_FSR) is used in AM335x ICEv2 board.
It means PRU1's pin is not used. and PRU0's pin is used.

Is it correct?? PROFIBUS datasheet is wrong ?

Hi Hiroyasu-san, I think your interpretation is correct and we need to change datasheet to prX_prN_gpoY.
Thanks for pointing it out,
Paula

Hi, Paula-san

Thank you for your reply.
I understand EVM is correct and datasheet is not correct.
It need to change.

Thank you !

Hiroyasu-san, a quick comment (clarification), both PRU0 and PRU1 are used, though... Mainly, PRU0 is used for host communication, and PRU1 for UART communication.

thank you,
Paula
