TMS320C5504: Bootloader I2C EEPROM read operation

Tony Tang

Part Number: TMS320C5504

Hi, C5000 Apps.

My customer wants to use MSP432 to imitate the I2C EEPROM, the real C5504 binary stored in SPI flash of MSP432, when MSP432 release C5504 out of reset, MSP432 response to C5504 I2C read operation to read data from SPI flash then send back to C5504 via I2C.

Now want to know the C5504 bootloader I2C read operation detail. when use byte read, when use sequence read, etc, a flow chart would helps.

Tony,

There isn't anything special as it pertains to using I2C for the bootloader as long as you stick to correct I2C protocol standards. Please refer to the C5504 bootloader app note located at http://www.ti.com/lit/an/sprabd7c/sprabd7c.pdf Below are some I2C specific requirements that need to be adhered to.

Hope this helps.
