| Post subject: | Lima SPI for Flash Memory |
Hello! The Lima datasheet says to be careful when using SPI as it is connected to internal flash. I would like to use the SPI to interface to an external flash memory. The datasheet says to use CS1 or CS2. Is pin 19 brought out as SPI_CS CS0 or is it safe to use for my external memory? If it is not safe, which pins (GPIO I presume) act as CS1 and CS2? Thanks, |

Hi, GPIO5 is connected to internal flash memory.For external flash memory you need to use any different GPIO pin for CS. |
