I've opened a support ticket, but perhaps I can explain it here as well.
Part of this might be heritage related.
We use the four chip selects, and feed them into a demux to produce 16 outputs. We use this to talk to 12 SPI devices.
To operate this properly on the SOMRT1061, I can't use the chip ...

Hi Tom
Sorry. This is with the most recent NNDK 3.57, SOMRT1061.

In the DSPI Driver, a call to Init(..) will initialize the SPI almost as expected:

spi()->CR = LPSPI_CR_RST(1); // This statement causes the SPI to reset, Clock polarity and phase are set to 0.

The function returns with clock phase/polarity in 0/0. I then have to trigger the GPIO lines ...

Thanks dciliske, perfectly clear. I appreciate the explanation.

Hi Tom,

I understand -- on the old MOD5441X, I was already copying the memory mapped flash space to a location in RAM, so it's somewhat simple.
I'd just marked the end of the flash space as where I would store this extra data.
I was storing to an arbitrary place in flash which was significantly ...

I saw that the calls to FlashProgram and FlashErase were failing to compile and tracked down the Hal_StorageSave and Hal_StorageRead functions.

Hal_StorageSave on the MOD5441X seems to simply be a wrapper for FlashProgram and FlashErase which is great. Hal_StorageRead doesn't exist for the MOD5441X ...

This is probably what I'm looking for. I was running through the nbupdate.cpp code and didn't see any calls before the flashing occurred. I see they are in config_server.cpp.

Thank you.

I've been migrating some MOD5414X code from 2.x to 3.x and I was using the update_shutdown_func and the update_complete_func. I can't seem to locate similar function calls in the nbupdate.cpp file.

Am I missing something here, or are there plans to add these function callbacks? They're useful for ...

So.. Looks like I don't need to use the IRQ code, but the interrupt driven code is about 15% faster, at least how I'm using it, than the non-interrupt driven code, which should (?) be faster. MicroSD card access has fairly low priority in my application so this might be why the interrupt driven ...

I can't speak for 2.7.5 as I'm using 2.8.7, but yes? SPI0 is not brought out to J1/J2 other than CS3.

I'm not sure whether you need to enable the interrupt driver for it if you want to use SPI1-3.
Uncomment #define SD_IRQ_QSPI in MOD5441X\system\mmc_mcf.cpp if you do?
In porting my MOD5272 code to ...
