STPM33 configuration problem

[JZoha]

I'm using STM32F412 MCU connected via SPI bus to EVALSTPM33.

I downloaded en.stsw-stpm002 driver from ST.

All is fine till calling Metro_ApplyConfig.

Metro_Write_Block_to_Device transmits default configuration correctly.

Metro_Read_Block_From_Device receives default configuration correctly.

However, when I try to change the default configuration, (for example disable the CRC):

Metro_Write_Block_to_Device transmits user configuration correctly.

Metro_Read_Block_From_Device receives default configuration.

It seems that the configuration is not written to the registers.

What is wrong?

When you want to disable the CRC, your following commands must be aligned with the new configuration, so you must use a 4 bytes cast instead of 5.

Be careful also to send the right CRC value when you send your "CRC disabling" command.
