replacing the SPI flash

hi,

if I replace the SPI flash from 64Mbit to 32Mbit, do I need to modify the UBL code or not? if yes, where I could modify? and, where I could modify to increase the SPI read clock?

thanks

You should not require any changes in the UBL if it is the same SPI flash just in a smaller size.

The SPI clock can be increased in "spi_mem.c" in the SPI_MEM_OPEN() function. You can set the spiCfg.prescalar to be a smaller value which will increase the clock speed.

Thanks Jeff,

I read the code and found the value, by your confirm, I could easily modify the prescalar.
