Hi, NXP,
I use DMA transfer data form NorFlash to SRAM for image loading.
Confused about the time it spending on data transfer.
Transfer total 4MB data from Nor to SRAM:
1.Use eDMA_0 only, it spends 28ms
2.Use eDMA_0 to transfer 2MB and eDMA_1 to transfer remain 2MB at the same time, it spends 50ms
Why is the time increasing instead of decreasing?
Hi,
For S32G, it seems that the AHB interface is the limiting factor for eDMA under QSPI data transfers.
Please, let us know.
Hi,
Thanks for your feedback.
At what frequency do you have configured the QSPI interface for booting?
Please, let us know.
