Flash QSPI question

Post by Over_score »

To David and/or Michael:
In version 3.20 of DMCP there are new functions about QSPI: https://technical.swissmicros.com/dmcp/ ... _qspi.html
One of this functions is:

Code: Select all

int qspi_user_size(void)
The value returned on my DM42 hardware SN 3835 is 4096.
What are this 4096? Bytes or blocks of n bytes?
How many is n if they're blocks?
Is there a way to increase the size of the user QSPI?

Thanks in advance.
DM42 (SN 00284 & 03835), DM15L, HP41CV, HP42S, HP35s, WP34S, HP Prime

I've extended the documentation a little bit. Hopefully, it is clear now.
