AM3352: Pinmux utility for AM3352

Part Number: AM3352

Hi everyone,

Pinmux Utility(cloud) can not set the sdwp pin of MMC to Rx setting. (As below)

Is this bug?

Therefore, the following registers are not set to Receiver enable in am335x_pinmux_data.c.

When using MMC, is it not necessary to set Receiver enable of sdwp?
Or Is it a bug in the tool?

In the case of a bug, I will set Receiver enable manually.

Best regards,

Sasaki

    Hello,

    The write protect signal "sdwp" is needed for MMC external cards with mechanical write protect switch. So yes, in most cases it is necessary to set RX to enabled. That is, please set the Receive enabled manually for now. 

    Moving on to the tool, it looks like a bug. I will file an internal ticket for this to be fixed. That RX checkbox should be checked(enabled) and read-only (because if you use this signals it is input only anyway)

    Hope it helps,

    thanks,

    Alex
