Dear group I am doing a design with a C5402 DSP and flash memory module. Can someone give me some pointers to the logic control interface to the flash memory. The processor needs to boot from flash memory. SPRA585 recommends the use of the XF pin on the DSP, but as the DSP starts up with the XF pin HIGH, this will not work. Has anyone done a successful interface to flash memory with the ability to boot from flash? Rgds Jean Viljoen Development Engineer Azoteq (Pty) Ltd Tel: +27 21 863 0033 Fax: +27 21 863 1512 |

The documentation includes schematic. Also, if you search this group you will see a number of posts talking about FLASH boot and NV storage. Jeff Brower DSP sw/hw engineer Signalogic |
