AM263P4: Issue with synchronize MCAL Fls API Nor_OspiWrite

Part Number: AM263P4
Other Parts Discussed in Thread: AM2634

Tool/software:

Hi,

I am using AM263Px MCAL 10.0 in an Autosar project. I noticed that Fls function Nor_OspiWrite takes long time to write.

Because this function is not an async function, it is trying to write all the requested data in one go.

And this design is different with the Fls V0 version for AM2634 which using Fls_norAsyncWrite.

So question is:

1. Is there any plan to provide async writing function? or

2. If you have Async version for AM263Px, please provide to me.

Thanks

Hello Pheonix,

Interrupt mode is supported in INDAC mode for AM263Px. You can check performance data in respective user guide.
AM263PX (4.13. FLS Module — Documentation for AM263Px):

AM263PX

Time Taken to Write Sector of Size (4096 bytes)

3050us

AM263X (6. Key Performance and Memory Consumption Data — Documentation for AM263x):

AM263X

Time Taken to write sector of size(4096 bytes)

12ms

Thanks,
Gunjan

Hi Gunjan,

Interrupt mode does NOT stop the fls_erase/write Function to wait for the operation finish.

For example, if you enable interrupt mode, when doing erase, it will still calling into Fls_norBlockErase, then calling Nor_OspiCmdWrite,

Nor_OspiWaitReady one by one. can you see the loop here?

while(timeOut > 0)
    {
        retVal = Nor_OspiCmdRead(handle, cmd, cmdAddr, numAddrBytes, dummyBits, readStatus, numBytesToRead);
        if((retVal == (Std_ReturnType) E_OK) && ((readStatus[0] & bitMask) == 0U))
        {
            break;
        }
        timeOut--;
    }

As long as you have the waiting loop, it blocks the process unless you could explain it in other way.

Interrupt notification only change the jobStatus to Done, but it dosen't stop the waiting in the loop.

Hello Pheonix,

Fls_Erase doesn't support interrupt mode. Fls_read and Fls_write support interrupt mode.

Thanks,
Gunjan
