Boot LPC4330 from SPI/SSP: what chips are supported?

gertvierman — Wed, 04 Oct 2017 13:59:23 GMT

I just found out that the LQFP144 package can only mux the I2S1 through the same pins which are needed for the SPIFI, which I currently use to boot.

Alternative would be to boot from SPI/SSP instead of SPIFI. Does anyone have experience with this, and what SSP/SPI chips are know to be compatible with the LPC43xx boot rom?

Thanks,

Hi Gert,

We don't currently have a list of supported SPI flash devices, we have only tested QSPI. Compatability should be good with a wide range of SPI devices because SPI boot operates at a much lower speed.

Hope it helps!

Ok, thank you. I planned for the Atmel AT45DB161E on my board, I'll share my results here when I tested.

AT45DB161E boots successfully.
