I have a BF527 with SPI memory. I tried to follow schematics and pullup settings from EZ-Lite, but what is strange
is Blackfin's behavior:
- sometimes it boots...
- soemtimes it does not....; it hangs.
I have check the board and everything seems to be fine.
What I have noticed is that adding capacitance to SPI_CLK improves the problem.
I scoped the SPI signals - and there doesn't seem to be any problem with SPI.
Has anyone experienced a similar problem with external SPI memory?
Thanks and best regards,
