LPC4088 QuickStart Board SDRAM access

Is it possible to use the external SDRAM memory on the LPC4088 QuickStart Board?

I can't say for sure as I haven't tried it but I don't see why not. You would have to configure the EMC first using the information in Chapter 9: LPC408x/407x External Memory Controller (EMC) of the
NXP LPC408x/407x User manual (UM10562). The most transparent way to use the resulting dynamic RAM at address 0A0000000H would be to configure it for use as Heap RAM similarly to the way AHB RAM is used on some microcontrollers. See the topic Using the additional 16 / 32kB of RAM on LPC175x/6x MCUs in this forum for more information.

For LPC1788 (SK-MLPC1788) EMC works.

You can now download the source code for an LPC4088 QuickStart Board SDRAM read/write example from the Cortex-M4 Source Code sub-forum.
