Part Number: AM623

Hi,
max speed for SPI is 50Mbit/s. Can this max speed be used when SPI is used as boot flash device?

Holger, the ROM operates the clock at a max of 6.25MHz for SPI boot mode. You would have to use the other SPI boot modes (ie, xSPI, OSPI, QSPI) to obtain up to 50MHz operation from the ROM. Once into the bootloader, software can change the frequency in any mode.

Regards,

James

Hello James,

so, the tiboot3.bin would be loaded with 6.25MHz and the firmware image could be loaded with 50MHz from SPI flash?
