AM6422: R5F OSPI Startup failure

Tool/software:

Hello,

We use SDK version 8.6 and R5F real-time core. When I change to OSPI mode to start, sometimes the print message only prints the version number after startup, and the application no longer runs.

After powering on again, it will be normal.What could be the reason? We drew the hardware ourselves

Hi, wang:

follow this link:

uart problem during the boot. Solution: config uart from interrupt mode to polling mode, your problem of print will be gone.

Am I right? Vaibhav Kumar

Thanks

Hello Jun,

Lets wait for Wang's results to come out as a result of using UART in polled mode.
