TMS570LC4357: Diagnostic FLA11 triggers ESM 2.3 for single bit fault inject

Hi experts,

Our implementation of the diagnostic FLA11 behave as expected.
When triggering single bit error we get the expected ESM 1.4. Additionaly we get a ESM 2.3 which should not be triggered.

When implementing the diagnostic we used the SafeTi Library as a reference. Additionally we load the function into RAM as suggested by the Technical Reference Manual.

We do the following:

volatile uint32_t Val;
volatile uint32_t* Ptr = (uint32_t*)(FLASH->DIAGCTRL);

*Ptr = 0x50007U;

Ptr = (uint32_t*)(FLASH->FEMUDMSW);
*Ptr = 0x0U;

Ptr = (uint32_t*)(FLASH->FEMUDLSW);
*Ptr = 0x0U;

Ptr = (uint32_t*)(FLASH->FEMUECC);
*Ptr = 0xCEU;

Ptr = (uint32_t*)(FLASH->DIAGCTRL);
*Ptr |= (0 << 8U); // default value is 0 anyway

*Ptr |= (0x1U << 24U);

/*Trigger error with flash read*/
Ptr = (uint32_t*)(0x00000008U);
Val = (uint32_t)*Ptr;

Is a ESM 2.3 expected or is there something we are missing?

Thank you and best regards,
Max
