Dear All

Need to develop a second bootloader for the RT1064, looking for datasheet on the internal flash. Or any APIs? examples?

Thanks!

Hi

The QSPI flash in the 1064 is a W25Q32JV and so its data sheet can be used.

A ready-made, documented and supported secondary loader (including USB, Ethernet, UART, I2C, SD card, Memory stick loading) and supporting OTA of AES128/256 encrypted firmware for operation in internal RAM, SDRAM, XiP and on-the-fly decrypted XiP is available for the i.MX RT 1064 (including QSPI flash API for for file system and parameter system use) in the uTasker project:
