AM2634: Enable QSPI interrupt mode during Boot

Xiaoqiang Sun

Part Number: AM2634

Hi,

I test the demo - sbl_qspi_am263x-cc_r5fss0-0_nortos_ti-arm-clang

In this demo, the QSPI interrupt mode is disabled. The flash code read costs too much time.

I wish to run other function in SBL during the code reading from external flash. I think QSPI interrupt mode could help me achieve this.

How can I enable the QSPI interrupt mode. Is there a demo project?

The driver does not supports interrupt mode as of now.

Which part of the code you think is taking more time ?

The QSPI read is done via memory map read which is a faster mode.

Can you share more details here.

Thanks and Regards,

Another suggestion would be to use DMA to optimize the performance and use the interrupts of eDMA which is already supported in the driver.

Hope that helps.
