How to port "SPI_FullDuplex_ComDMA_Slave" to "TFM_SBSFU_Boot" on STM32U585

[zqizh.1]

Hi,

I want to port "SPI_FullDuplex_ComDMA_Slave" to "TFM_SBSFU_Boot".

My MCU is STM32U585.

I can port "SPI_FullDuplex_ComDMA_Slave" to "TFM_Appli NonSecure" success, but fail to port it to "TFM_SBSFU_Boot".

Do you have any suggestion for it?

Please advise.

Thanks,

QiZhang

Hi QiZhang,

which kind of error message you got ?

I guess there are configuration issue of security for SPI + SRAM + GPDMA.

Refer to RM0456 Rev chapter 5 Global TrustZone controller (GTZC), 5.6.2 GTZC1 TZSC secure configuration register 1 (GTZC1_TZSC_SECCFGR1) for SPI for example.
