Is there EEPROM emulation in STM32CubeF4?
Page http://www.st.com/web/en/catalog/tools/PF257902 has status NRND and
recommends use STM32CubeF4, but I don't see EEPROM emulation in those bibls

The NRND is a bit self serving, the old firmware is still viable, and has a large installed base. The task of porting to the month old Cube platform is not insignificant, and not without risk.

Who has ported program for new HAL bibls?

Hi Victor,
The EEPROM emulation application for STM32CubeF4 is under development, it will be available soon.With regards!2014-06-03 07:46 PM
Hi!
How soon will it be available?
Can I get beta (development) version?2014-10-10 06:04 AM
Hi,
Is this available yet? Thanks2014-12-16 05:38 AM
Hello ST,
when will this be released? I need to make a decision to either wait, port to cube lib on my own, or use external EEPROM.2014-12-16 07:50 AM
Or just manage the FLASH, as FLASH, and avoid all the complications and confusions of pretending it's EEPROM

Unfortunately, I need the wear leveling feature of the software. As a temporary solution, I managed to squeeze the old SPL flash driver into the HAL/CMSIS environment. It works but I don't like it.

I have a problem with writing to and reading from the user configured section of flash memory through hall_stm32f4xx library. After I wrote a value to the starting address of the user configured memory , I read it null or (not saved after programming).
This is the code void writeFlash(void) { HAL_StatusTypeDef status; status = HAL_FLASH_Unlock(); status = HAL_FLASH_Program(TYPEPROGRAM_HALFWORD, (uint32_t) userConfig, status = HAL_FLASH_Lock(); } void readFlash(void) { tempvalue = *(uint8_t *)(userConfig); } and this is the part of the linker for the user configured flash MEMORY { RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 128K CCMRAM (xrw) : ORIGIN = 0x10000000, LENGTH = 64K FLASH1 (rx) : ORIGIN = 0x08000000, LENGTH = 32k DATA (xrw) : ORIGIN = 0x08008000, LENGTH = 32k FLASH (rx) : ORIGIN = 0x08010000, LENGTH = 512K-64k FLASHB1 (rx) : ORIGIN = 0x00000000, LENGTH = 0 EXTMEMB0 (rx) : ORIGIN = 0x00000000, LENGTH = 0 EXTMEMB1 (rx) : ORIGIN = 0x00000000, LENGTH = 0 EXTMEMB2 (rx) : ORIGIN = 0x00000000, LENGTH = 0 EXTMEMB3 (rx) : ORIGIN = 0x00000000, LENGTH = 0 MEMORY_ARRAY (xrw) : ORIGIN = 0x20002000, LENGTH = 32 } SECTIONS { /////// > FLASH /////// > FLASH1 .user_data : { . = ALIGN(4); *(.user_data) . = ALIGN(4); } > DATA /////// > MEMORY_ARRAY /////// > RAM }
