AM62P: Regarding the configuration of the OLDI output pin in the AM62P

Q W

Part Number: AM62P

Tool/software:

As shown in the figure, I want to output images using two lvds channels. OLDI supports a total of 8 data output channels. How can I configure the first 4 data channels for channel 1 and the last 4 data channels for channel 2?The relevant pin allocation was not found in the official example.

The pins of OLDI are as shown in the picture

Hello Q W,

Please refer to the sections:

Section, DSS LVDS Interface of the AM62Px TRM for the DISPC source video port, format and timings

Section, OLDITX Output Mode Configuration of the AM62Px TRM on the possible OLDI interface output mode configurations.

In particular at the DSS VP1 port to OLDI_TX0 and OLDI_TX1 connectivity level, the mapping seems to be controlled from the DSS_VP1_DSS_OLDI_CFG register bitfields.

I hope this answers your question.

Thanks

Kind Regards,

Anastas Yordanov

The question is not clear.

In case the query is to use single lane per single line. i suspect this is not supported.

OLDI interface supports

OLDI (LVDS) (1x OLDI-DL, 1x or 2x OLDI-SL),

May I ask if there is a corresponding relationship between OLDI0 Output and OLDI1 Output and the pins in the following figure?For example, OLDI0 Output corresponds to the 8 pins AE20 to AE19, and OLDI1 Output corresponds to the 8 pins AD17 to AA16

I assume you meant you want to use the x2 single link as x1 dual link.

This is supported.

Is your question related for single link or dual link?
