Disabling TImer5 & 6 in CPSW driver in EZSDK 6.0

Other Parts Discussed in Thread: AM3352

Hi Team,

My customer  is designing on AM3352, the SDK version they are using is EZSDK 06.00.00.00. They found timer 5 & 6 are used in CPSW driver(CPSW_RX_TIMER_REQ, CPSW_TX_TIMER_REQ in CPSW.c), what customer already use as PWM output. But Ethernet can’t work properly if they use timer 0 & 3 to replace or disable timer directly. I can reproduce this issue on EVM, AM335x can’t get IP address successfully once I change/disable timers.

I found it is just a workaround for PG1.0 as errata mentioned, customer is now changing to PG2.0. So could you let me know,

1. Is there a patch to disable timers in ethernet drivers?

2. Or how to change to use Timer 0 & 3 to replace?

Thank you.
