I’ve configured MCU Boot in FSP3.8.0 to use external QSPI for the secondary slot which works when not coded. Still, if I enable ECISE encryption in RASC and put an coded image in the secondary slot in QSPI, MCU Boot will tell me that both the primary and secondary images aren’t valid. I’m encrypting with the python image tool using the test keys without any error from the tool. Does anyone have any ideas?

    Hi, What have you got the heap set to in the BSP settings? For ECIES more heap is needed than just ECC and AES along. Try 0x1000 and see if it works( doesn't need to be this large but reduce it once it's working). If you still have problems let me know and I'll put a demo together.

    Hi , The RA4M1 does not accept external parallel buses.  In order to add external memory to this device, for instance, you would need to use the IIC or SPI interfaces. Thanks

Hello, I am writing a charge haul for the RA6M2 processor. To do that, I need to do variations to startup.c, so I was wondering what the proper way of doing this is. Should I just modify the being startup.c in place? If I do so, is there any chance that it’ll be regenerated in its original form by the figure system?

Or the other volition I can suppose of is, count the startup.c from the figure( the right click menu has this) and produce a blank startup.c and colonize it with my code.
The reason for this is that I want to produce special vector functions that” forward” the intrude to either the charge haul itself or to the operation.

    Hi, The simplest way to guarantee that any changes you make to a FSP configurator generated line is to copy the line to the src folder and also count the original from the figure. Then also you can make the changes without the trouble of them being overwritten.

    The MCU installed in the EK- RA4M2 is the same as yours but have 100 pins rather of 48 pins. So I suppose the code illustration of the EK- RA4M2 should also work on your custom board without changes.

We have got the HAL code for the driver, but are there any examples of what to fill the waveform memory with to get certain effects? That would be super helpful rather than reinventing that wheel.
