Re: flash write speed very slow

the 10S record is external 512kB spi flash
the 30S is internal 2MB QSPI flash
that means everybody using internal QSPI flash will need over 30s to flash one xmos XUF chip?
can I skip the erases entire flash step?
garbage in the remaining unuse flash area should not affect anything

Re: xCORE-AUDIO Hi-Res DAC/HPA Platform Hardware(DAC) volume

It's also the great of XMOS, there are room left for the developer to enhance, not all xmos product are the same.
