FEE read problem

tianxing — Fri, 17 Dec 2021 09:15:21 GMT

I found a problem when I debug the S32K344 FEE code.
If we write 4 bytes data we need the define a 6 bytes variable to read it or else
we cannot get the correct data.Why this happened?
The source code is as below
uint8 Eeprom_1[4];
uint8 EepromRead_1[6]={0};

for(uint8 i=0;i<4;i++)
{
Eeprom_1[i]=i;

}
Fls_Init(NULL_PTR);
Fee_Init(NULL_PTR);

while(Fee_GetStatus()!=MEMIF_IDLE)
{
Fls_MainFunction();
Fee_MainFunction();
}
Fee_Write(FeeConf_FeeBlockConfiguration_FeeBlockConfiguration_0,Eeprom_1);
while(Fee_GetStatus()!=MEMIF_IDLE)
{
Fls_MainFunction();
Fee_MainFunction();
}
Fee_Read(FeeConf_FeeBlockConfiguration_FeeBlockConfiguration_0,0,EepromRead_1,4);
while(Fee_GetStatus()!=MEMIF_IDLE)
{
Fls_MainFunction();
Fee_MainFunction();
}

Please, could you share with me the Fls configuration you're using?

Best Regards,

Hello @tianxing,

I have tried your project, unfortunately I wasn't able to reproduce your issue: I modified the EepromRead_1[] to have only 4 bytes, still I could see the read data was correct (I also tried with other programmed data). See below snapshot:

Except the modification of the store buffer and the comment out of FlexCAN (I didn't configure FlexCAN receiver node), I didn't change anything and just re-compile the project. I have attached the project after modified.

Best Regards,

Nam

Thank you Nam

May be it is the JLink problem,I used the V9 JLink cannot work well with S32K344

And we bought V11 to solve this problem.
