Should ICACHE be invalidated when a double ECC error occurs?

PieterG · 2024-06-06

In the FLASH_ECCDETR register, the ADDR_ECC field description contains:"The address in ADDR_ECC is relative to the flash memory area where the error occurred(user flash memory, system flash memory, data area, read-only/OTP area)."But I'm having troub...

I'm trying to use the STM32H563 HASH peripheral to speed up sha256 calculations.The examples all use HAL_HASH_Start() to write the entire message at once.However, I'd like to feed chunks of data to the peripheral. The OEMiROT mbedtls sha256_alt drive...

I'm trying to use CMSIS DSP on a STM32H563, but I do not get the expected results.In X-CUBE-ALGOBUILD.1.3.0, when I select DSP Library in STM32CubeMX, the installed arm_math.h does not list Cortex-M33 support: #error "Define according the used Corte...

I am using an stm32h563 nucleo 144 board, and I am frequently running into the issue that after a power cycle the LSE does not start.This is the relevant part of my SystemClock_Config: LL_PWR_EnableBkUpAccess();while (LL_PWR_IsEnabledBkUpAccess () ==...

Thank you @Sarra.S for your answer.I guess invalidating the ICACHE is only necessary when ICACHE is enabled for the flash sector in which the error occurred? (in other words, I do not have to invalidate ICACHE for double ECC errors in OTP / EDATA for...

Am I the only one struggling with this?Or is everyone just ignoring ECC error NMI's?

@Sarra.S Can you please point me to where this knowledge base item explains whether ICACHE should be invalidated on double ECC errors?Or alternatively a simple yes or no answer would also be very helpful.

Maybe I've overlooked it, but I have read the article several times and it does not mention how ECC errors are to be handled? I am quite sure that I read about invalidating ICACHE after a double ECC error, but I cannot find it anymore in the official...

I have tested without chunking, and as expected the HASH peripheral still works.As long as we feed a multiple of 4 bytes of course. Because the data can be written directly, memcpy is avoided. So I prefer not to accumulate data in 64 (68) byte chunks...
