Can someone confirm that I am able to boot the TMS320C5515 from a S70FL256P (256-Mbit CMOS 3.0 Volt Flash Memory) as long as I connect it to CS0? Anyone have any suggestions? According to the following it looks like I'm OK.
Please see our C5505 bootloader appnote, Using the TMS320C5505/04 Bootloader:
“The bootloader supports booting from an SPI EEPROM with the following requirements for the external
device:
• The device must support at least a 500 kHz SPI clock.
• The device must be connected to SPI CS0 and act as an SPI slave.
• The device uses 2 bytes (16 bits) for internal addressing (up to 64kB).
• The device must have the capability to auto-increment its internal address counter to allow sequential reads from the device.
• The device can be connected to either valid pin-mapping for SPI; there are two distinct pin-mappings available. The bootloader attempts to communicate on each SPI pin-mapping, one at a time."
The SPI EEPROM should support 16-bit addressing and 8-bit data.
