TPS65987EVM: Flash update over I2C libraries

Hi Tim,

Please refer to the Host Interface Technical Reference Manual for the list of registers and relevant 4CC commands.

Thanks,

Emma

Hi Emma,

Thanks for the quick reply.  I am already aware of the Host Interface Reference manual and would like to take advantage of the example C code.  However, the C code appears to reference library functions and would like to get those.  For example:

1.       USB-C PD AN SPI Flash Over I2C – slave21a.pdf

Example code on page 7, 8, 9:

1. retVal = ReadReg(REG_ADDR_BOOTFLAG, REG_LEN_BOOTFLAG, &outdata[0]);
   1. retVal = WriteReg(REG_ADDR_PORTCONFIG, REG_LEN_PORTCONFIG, &indata[0]);
   2. retVal = ExecCmd(FLem, sizeof(flemInData), (int8_t *)&flemInData, TASK_RET_CODE_LEN, &outdata[0]);

Are these functions, part of library? If , Yes – Where is definition and library of functions (document)?

1. USB-C PD AN FW Update Over I2C – slav783a.pdf

Page 7.

C file containing the fundamental global functions used for controlling the

TPS6598x:

1. ReadIICRegister() ¨ I2C Read . A generic I2C read function that can be used for any register of the TPS6598x
2. WriteIICRegister() ¨ I2C Write . A generic I2C write function that can be used for any register of the TPS6598x, using the register length and data as an input
3. fourCC_Command() ¨ 4CC Commands . A case statement uses the switch() operator using selected 4CC variables required to perform the FW update

above 3 function need this    HostCommandSend(&i2cMessage);

                is it part of libraray or .dll?

I also tried downloading SW-TM4C but could not find relevant functions in there either.

Thanks,

Tim

Hi Tim,

Let me check with the team. I will get back to you in a few days on this question.

Thanks,

Emma

Hi Tim,

After talking with the team, this is sample code that can be used with Tiva microcontroller, the TM4C123GH6PM. We do not have the specific libraries. Please try investigating the Tiva libraries to see if you can find what you are looking for. 

Thanks,

Emma

Hi Emma,

We did not find any relevant libraries.

Thanks for checking,

Tim

Hi Tim,

No problem. Hope you can find what you are looking for. 

Thanks,

Emma
