Hi Mr. Kim,
Thank you for your patience. Unfortunately, with the custom board and different eMMC part being used, we cannot replicate this to see if placing a 10~20pF capacitor is a viable fix and will not cause other issues. Therefore, I cannot recommend…
Hi, Nicholas
Is that of template "J721e_TPS6594" in the GUI correct? Is it really can be uased ?
I reference the design package of "PROC078E8C_RP" and "PROC079E3D_RP" .

The VSYS_IO_3V3 is generated via a load switch on the SOM module. It is controlled via the PMIC (part of the processor's power-up sequence). It appears none of the PMICs supplies are turning on. Its possible the PMIC detects an error when it tries to…
Part Number: PROCESSOR-SDK-J721E We are using Jainto 7 board for our usecase. When i2cdetect command is executed, it shows 8 channels from 0 to 7. I n the attached document, there is an i2c tree diagram. In the i2c tree, we only see only 6 buses. Please…
Hi Tim,
Thanks for your help! but we have one "failed" PCBA only, and it is being used to debug the USB3.0 issue now, we need more time to debug LM5141 after we finish the USB3.0 issue.
By the way, the buck regulator design of LM5141 is copied from…

toshiki kouzai said: Is there a pinmux table available for MMC2? I searched through the TRM but was unable to find it. Is it not documented there?
The pinmux table for MMC2 interface is shown in the J722S datasheet. I am attaching the…
