Any help? Got trouble with Spi Flash Boot mode.
I'm using the superspeed explorer kit -003 with a flash(16M) connected to Fx3.But i got some trouble when trying to boot from Spi. I did all steps under the instruction of spi boot section in the AN76405 EZ-USB @FX3 Boot Options,pdf.
Of course ,the superspeed kit-003 itself doesn't support Spi Flash Boot mode because it has no flash chip on its board. But i just want to use another external flash chip for boot . Firstly, i programmed the Fx3BootAppGcc.img down to the chip by using the Program > FX3 > SPI FLASH Options in Control Center . It displays “Programming of SPI FLASH Succeeded,” Then i changed the Pmode by changing the Outpin(pmode 0,1,2) to '0 z 1' so it can boot from spi. then just reset.
But it just failed . So,what's wrong ?Is it possible to boot from an externl flash chip with this board??
I'll be very thankful if this post gets any reply.
