各位专家 好!
请问dsp出厂自带的Bootloader支持哪些SPI FLASH呢?
例如,TMS320C6748开发板通常外接的SPI FLASH是W25Q32,如果我换成AT25F2048或者IS25WP080D,出厂自带的Bootloader还能支持吗?
如果不能支持,那该怎样做才能保证正常使用呢?
期待您的指导!
谢谢!

ROM bootloader SPI boot mode对SPI flash的要求如下:
SPI EEPROMs must use 16-bit addressing, while SPI flash chips must use 24-bit addressing. The read command opcode for the SPI flash device must be 0x03.
