[hal][nrfx_qspi.c] Is it reasonable to check if 'p_buffer' word aligned in 'qspi_xfer'?

[Ben.su]

Hi Nordic guys,

I'm developing with nrf5340, and meet some problem with writing external flash - nrf qspi flash.

I found it sometime failed in 'flash_area_write' and return -22.

And I debug and find that, in qspi_xfer, line 99 at 'modules/hal/nordic/nrfx/drivers/src/nrfx_qspi.c', it check if the write data buffer's address is word aligned!

That's why it failed at writing nrf qspi flash.

In my opinion, it need to check aligned with 'address', but not 'p_buffer'.

Will any body help and fix me?

Sure, I have filled the buffer into another empty buffer, that works fine.

I'm just curious about why the buffer address should be aligned.

If that's the easyDMA protocol, that's it.

Thanks Simon
