I am attempting to boot an BF547M DSP from an M25P64 SPI flash. I am able to read/write/erase this flash without issue.
The BMODE = 0011. I have put a probe on the flash and have been able to see that the DSP will attempt to read from the
flash with an 0x03 followed with a number of 0x00 bytes. The MISO seems to contain the correct values from the flash.
After a few bytes the DSP HALTs. Attached is a scope shot of what the DSP is reading in.
Anyone have any suggestions on other things to try?
