These days i failed to boot a C6727b via a W25X32 SPI flash chip which belongs to the WINBON company. I succeeded to boot C6747 via the same flash last year. I connected the flash to SPI0 pins(4-wire mode using CS), and accomplished the erasing, programming and reading operation. However,when i used a oscilloscope to detect the flash's DO at power-up after burning, there was not any data signal be catched. I also detected the flash 's DIN and the first 8 bits were 0x03, followed by 24 zeros, then the CS went up.
Could any one tell me whether the C6727B could boot from this flash? Or how can i settle this problem?
Thanks a lot!
