Hello! Does anybody succeeded in booting BF-532 using SPI AT45DB041B? We ar experiencing problems.
Description:
I wrote a sample led blinking program using VisualDSP++ 3.5, and debug i using JTAG, it works well. Later, I selected a DSP loader file target an I've got an .ldr file. The options used was SPI INTEL HEX, default star address, no boot kernel. Then, I programmed it into the flash, usin external programming device, and after manual blackfin reset, boot proces is initiated, but not finished. When I used my oscilloscope a bit, I saw that Blackfin sends SCLK, #CS an data signals to flash, but the flash responds only a few cycles (3-4 bytes I think). What the problem may it be? PS: I use blackfin as SPI master (BMODE=11)
