Hi, I'm collecting and saving small amount of data (about 64 bytes) once per
5 minutes on MMC sector. I put my data into increment pointer in SRAM memory, but I can't wait to fill 512B buffer. I have to save my data (512B buffer) on each collected data due to power lost. If I fill 512B SRAM buffer - I use next MMC sector. I use SPI mode and sector data is set to 512 bytes. I need to investigate - how the MMC card internal controler writes my data to MMC NAND memory. Does it erase 512B NAND sector on each my write ? or just in case ?... hmmm. Every information will be priceless :)- posted
