Hello,

I supposed you're using S32K1xx ASR 4.2, and just update from RTM 1.0.0 to RTM 1.0.4. Since there might have a lot of changes between these two versions, could you send us the EB configuration files in *.epc, including SPI, MCU and PORT? We will double check in our site.

Best Regards,

Nam

Thank you for the replying.

Yes I just update from RTM 1.0.0 to RTM 1.0.4, since the setting is almost the same.

after installing the new mcal with 3rdPartyMcalIntegrationHelper, I use the .arxml file to import the setting directly.

attached file is the .arxml file of spi, mcu and port, hope it could useful.

by the way, I tried to set TCR as 00200007 after Spi_Init().

but it didn't work either, please check the attached 1.jpg

thanks!

Hello,

I have imported your configuration and test with my board. Unfortunately, I can't reproduce your issue. With this sequence: Sigma300_ProgramWritesSequence, (using SPI0 CS0) I can send the SPI signal from master. I also able to modify the TCR register's value.

Best Regards,

Hi Nam

could you send me your generate code?

I want to compare the diffference.

Hello,

Here is the generation code. You can check whether it's different than yours.
