AM2434: LP-AM243 PROC109E3 PDF and DSN do not match

John Ford

Part Number: AM2434
Other Parts Discussed in Thread: LP-AM243

I'm designing a processor board based on the LP-am243 launchpad, and I've made a bunch of notes on the .PDF included in the design information package. However, when I open up the .DSN schematic, the PDF and the .DSN do not match.

For instance, on Page 21, the resistor trees for setting boot modes have been pruned with some resistors marked DNI, while the schematic (.DSN) shows them in there with their normal values.

Is the intent that the PDF shows the as-built condition of the LP-AM243? Otherwise, are they equivalent?

Thanks!

John

Hello John,

Thank you f0r the query.

The DSN is representation of the design.

The PDF is representation of the variant

When you reuse the design and make changes to the DSN file, the DNI configurations are reset.

The recommendation is to refer the PDF and configure the DNIs.

Hello John,

Please refer to the FAQ.

https://e2e.ti.com/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/1518447/faq-am2434-am2432-am2431-alv-alx-custom-board-hardware-design---design-and-review-notes-for-reuse-of-tmds243evm-or-lp-am243-schematics

There may be some errors or improvements that may be observed and some changes may be required for improved performance.

The changes have been added as D-Note in the PDF schematic that has been embedded.

The recommendation is to refer PROC109A(001)_SCH.PDF schematics, read through the D-Notes and update the design accordingly.

Please add an E2E query topic wise to be able to support as required.

Regards,

Sreenivasa

Thanks! I thought that the E3 version was the latest, but I recently bought an am2434-LP board that was a A(001) version. I thought maybe I got an older version, but it seems that's the one to use as a model, then?

Thank you for the quick answers to my queries. I started work on this in October, but put it aside and I had forgotten about the FAQ posts. They are very useful!
