Part Number: AM625

Dear TI- Support Team,

In the E2E Thread https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1398125/am62a7-dss-pixel-clock-cannot-go-below-16mhz-small-displays-don-t-work

a fix for the Clocking issue with small displays is mentioned to come with the next SDK release.
Can you please tell me if the issue has been fixed and which TI DM Firmware version (git commit id) has to be used at least to aviod this issue.

Thank you and Best Regards

Tim

Hi,
Yes, this issue has been fixed, but do note, that the minimum pixel clock needed is 7MHz (hardware restriction).
This was resolved in 10.1 SDK: https://software-dl.ti.com/processor-sdk-linux/esd/AM62PX/10_01_10_04/exports/docs/devices/AM62PX/linux/Release_Specific_Release_Notes.html#issues-resolved

For more help, please refer this thread: AM625: DSS pixel clock can't set less than 15937500 Hz

Hi Tim,
No, we currently do not have a documentation for this, but I'll raise a request to include this.
Thanks.
