I also have the RT1050 board, I have updated the SDK for the RT1050 and also the Peripheral Tools are not available. For me it is essential to properly configure all peripherals, SPI, SDIO, DMA, interrupts ...
When will the Peripheral Tools be available in SDK for RT1020 / RT1050, or has anyone managed to have access to these tools even for the RT1050, which has been on the market longer?
