TDA4VM-Q1: Mcal fls and spi config

Hello,

1)

You can set "flsBaudRateDiv" and "blockSize" from the configurator.

Please refer example at mcusw/mcal_drv/mcal/examples_config/Fls_Demo_Cfg/output.

2)

Based of SPI_DMA_ENABLE ,Spi_IrqUnitMcuMcspi0TxRx or Spi_IrqUnitMcuMcspi0DmaTx,Spi_IrqUnitMcuMcspi0DmaRx Api will be called.

Sorry  I am not exactly clear of your second point. Could you please elaborate ?

Hello，Now I use Davinci config to set "flsBaudRateDiv" and "blockSize". I want to know how to use the param.and the spi module,I show you the code in file "Spi_Cfg.c":

Hello,

1)"flsBaudRateDiv" and "blockSize" TI internally added not AUTOSAR Specifications.

if you click on "flsBaudRateDiv" you see the description and information   

This is a baud rate divider to adjust the OSPI clock frequency .By default we are selecting '0' which adds +1 internally.

if you click on "blockSize" you see the description and information 

This is to select OSPI block size based on different variants.

2) I have generated using EB tool now, I am not facing redefinition error

I hope you are using MCUSW_02_00_00_06_CONFIG.

Hello，Now I am using the MCUSW_02_00_00_06_CONFIG  SDK0805 which add the param "flsBaudRateDiv" and "blockSize", Do you mean that  ospi clk now use FlsOspiClkSpeed/(flsBaudRateDiv+1) ? and the OSPI block size is just determined by soc , not the flash? In the spi module ,I set two SpiExternalDevices,I wonder if it has something to do with this setting. I show you thew rules in the mcal files:

Hello again,

Yes.

Yes it might be because of 2 external devices to 1 HW unit. You can connect one external device to another  SPI Hw unit instance and see you are facing the problem

Hello,we have two  spi slave devices which connect with one master spi master using different cs line. What can I do with this?

Pengfei Yuan,

I will raise an internal ticket to fix this bug .As a work around you can delete those re-definitions manually.

Thank you for informing us.

Hello, thanks for your reply!

Hello，when I debug the ospi flash driver, I find that the file "Fls_Cfg.c" is changed: the value of param  ".sectorStartaddress"  is 0, but in sdk0805  it is 0x50000000. In the function "OSPI_dac_xfer_mode_read", I find the value of param  ".sectorStartaddress"is used for "LLD_REG32_WR(pDst + i, LLD_REG32_RD(pSrc + i));"，So I think the correct vaule is 0x50000000.May you help me check the modification?

Hello,

Can you please raise this as an another E2E question  because this is different from initial question asked?

Hello,

OK,Thanks.
