DSP56720 Boot SPI EEPROM

daleulan2 — Mon, 03 Jun 2024 22:20:55 GMT

I am wondering if anybody knows what pin /CS should be coming from for a boot SPI EEPROM for the DSP56720? I know this is an older DSP but I have a handful of trays of them I'm trying to use up for a some low-volume DSP products. A bootloader listing would be fine, too, I can read the code pretty easily. Thanks!

Yes, this is perfect. I can hook the EEPROM up based on this and get my PCBs made. I am booting from serial EEPROM in an 8-pin DIP socket initially, then I have a SMD flash on the external data bus as well as a few megabytes of SRAM for delay. I should be able to boot from either the soldered-down parallel flash or the serial EEPROM.
