Tool/software:
Hello,
I had a very basic query on the AM2632-Q1 / Sitara series micro-controllers & wanted to confirm on my query.
Do we have an on-chip flash or any non-volatile memory in the series. I have gone through the datasheet, saw the eval board schematics as well. It is clear that an external nor flash (via QSPI) needs to be connected. Am I right?
If so, it would be interesting to know the rational of not having the flash on-chip. Any hints?
Thanks
Hi Dheeraj,
Thank you for the query.

AM263X series does not support on-chip flash.
I have gone through the datasheet, saw the eval board schematics as well. It is clear that an external nor flash (via QSPI) needs to be connected. Am I right?
Yes, your understandings are correct. AM263X have a QSPI interface (Serial).The one instance of QSPI in the device is primarily intended for fast booting from quad-SPI flash memories.
Please refer to AM263X TRM section 5.3.1 BOOTMODE Pin Mapping to see the supported boot modes in AM263X
AM263X also features GPMC - General Purpose memory controller (Parallel) a unified memory controller dedicated for interfacing with external
memory devices like:
•Asynchronous SRAM-like memories and application-specific integrated circuit (ASIC) devices
•Asynchronous, synchronous, and page mode (available only in non-multiplexed mode) burst NOR flash devices
•NAND flash
•Pseudo-SRAM devices
Please refer to AM263X TRM chapter 13.3 Memory interfaces for more details regarding the supported memory interfaces in AM263X
