@akirara said in Kendryte with external RAM interface?: K210 SPI0 SPI1 SPI3 support XIP , you can connect PSRAM up to 16M(SPI0 1 3) or 32M(only SPI3) As far as I know, there are only 16Mb (2 Mbyte), 32Mb (4 Mbyte) and 64Mb (8 Mbyte) SPI PSRAM chips on the market at the moment. Please correct me if I'm wrong. Is there any information about how to use K210 SPI XIP feature?
