Hi, We are using STM M24256-DFCS6TP/K 256-Kbit serial I²C bus EEPROM. We want to read and write the whole memory inside the EEPROM data. Are there any commands available in the u-boot and kernel test? and also if I want to read a particular location ...
I'm trying to find an embedded solution to replace an SD Card.Basic non-volatile memory, I2C or SPI read/writes.I spotted ST NVRAM, but can't seem to find much about it - is this a new or discontinued product?Are there any other options that I should...
Hi, I am trying to store and retrieve data in the M24C02-RMN6TP, however, I only read 255 when trying to read data. Using an oscilloscope shows that the address and data bits are transferred correctly, and the eeprom acks for both the address and the...
Dear ST-Community,this is my first post, so: Hello!I am currently struggling with a M2425 256kbit Eeprom that i want to address via I2C. I2C-access is working and i can read and write.The part i do not understand is the addresses of the memory. The E...
Hello Team,we have a board with 5x I2C devices on it. So far it works fine but we have a strange effect.We have 1x M24C02-FMH6TG (0x50 --> fixed??) and 1x M24C64-DFMC6TG (0x54 -> fixed!) from STMAdditionally we have further devices like temperature s...
Hi,I am using M34E04 I2C EEPROMread and write access works fine but I cannot enable write protection I have verified the WC pin is in the right state (logic 1) but I can still write to the device at this mode Any tip?RegardsAssaf
