Could Blackfin CPU support 32 bits address SPI flash ?
Currently the CPU we used is bf536, the datasheet says it can support boot from 24 bits address SPI flash. That means that it could only boot from Flash which its size less than 2^24=128M bits=16 MB.
Currently, we want to use a 256Mb=32MB SPI flash, Can bf536 boot from it? Which Blackfin CPU support it?
Newer Blackfin derivatives like ADSP-BF51x, ADSP-BF52x & ADSP-BF54x support 32-bit addressable devices.
OK. Thanks! So you mean that the bf536/537 could not boot from 32MB spi flash, right?
If so, do ADI have a chip upgrade plan which can let bf536/537 support 32MB SPI flash?
features are rarely added to older bootroms. only bugs are reviewed and fixed. so the chances of adding any new functionality at all to any BF53x part is pretty much 0.
