Hi TI Experts,

I am starting a new board design and planning to use TI Starter Kit (SK) design files for designing my custom board.

Hey,

we use the AM6254 with the TPS6521901 PMIC. Our Yocto BSP is based on 09.02.00.005 and we applied the 1.4 GHz OOP for our board. This new OPP requires a higher VDD_CORE and therefore we bumped buck1 from 0.75 to 0.85V.

We found two e2e threads [1, 2] which mention we shouldn't change VDD_CORE after released from reset. I was not able to find this limitation in the AM62x Hardware Design Guide nor the PMIC manual. Moreover, the BeaglePlay uses TPS6521903 (VDD_CORE=0.75V like TPS6521901) with the same device-tree entries for 1.4 GHz.

We will follow the advise from [2] and increase VDD_CORE in U-Boot. However, [1] is not making a clear statement why we can't increase VDD_CORE during runtime. Could you please explain why this is not allowed?

Best Regards,
Daniel

For SDK 9.0 to latest, we see that the GTC frequency in the SBL boot flow is 250MHz, whereas in the SPL boot flow it is 200MHz. How to set the GTC to 200MHz in SBL?

Why is my basic GStreamer encode pipeline failing as a result of "Failed to allocate required memory" in Edge-AI 9.1 SDK?

Hi 

We are having trouble achieving the input slew rates of 2.64V/ns ... 5V/ns for the RGMII signals defined in the AM62x Rev B datasheet (SPRSP58B), Table 7-33.

Are the values correct for 1.8V? Because the RMII interface, which uses the same pins, differentiates between 1.8V and 3.3V...

I also have another question for my better understanding. Is the input slew rate calculated from 10%/90% or 20%/80%?

Thank you very much and best regards
