TMDSEVM6678: Where is the sbl code location in eeprom?

KSH

Part Number: TMDSEVM6678

Tool/software:

The eeprom on the evm board contains a bank of 0x50 containing the I2C boot code and the PLL initialization procedure.
bank at 0x51 contains the second level boot loader program.

Where is the code for the second boot loader?

seonhyeok Kim,

I would recommend you to use the latest processor SDK 6.3:- https://software-dl.ti.com/processor-sdk-rtos/esd/C667x/latest/index_FDS.html

No need of SBL code for C6678. It is just the IBL code + the app code.

1. IBL code flashed into EEprom
2. The app code flashed into NOR/NAND.

The following FAQ has all the details.

Thank you for the reply. 
I am unable to use the latest SDK.
According to SPRUH58 documentation, the sbl bootloader is in eeprom. Can't find this code?

Hi,

Please specify the page number in SPRUH58 document ( where you have come across the SBL.)

Because, I do not find the mention of SBL in it !

IBL code is located here:- pdk_c667x_2_0_16\packages\ti\boot\ibl

Hello, that is on page 20 of SPRUH58.

Did I misunderstand?

Dear Customer,

Yes, That is SPI - Serial peripheral interface. Not SBL - Secondary boot loader.

1. IBL is flashed via I2C interface into the EEPROM memory flash.

2. The app binary is flashed via SPI interface into the NOR memory flash.

Hope this helps.
