TMS320C6657: NAND ECC Enable while using IBL

Lee Seung Hun

Part Number: TMS320C6657

Hello,

I am currently building and using the IBL from mcsdk_2_01_02_06 for the TMS320C6657.

I would like to enable NAND ECC and check the related logs during the boot process. However, I am not sure where the ECC configuration should be enabled when using IBL.

Could you please let me know which part of the code or documentation I should refer to for enabling NAND ECC and verifying the ECC status?

Thank you.

Best regards,
Lee

Hi Lee,

Can you refer: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1316902/tms320c6657-4bit-ecc-nand-error?, it might helps.

I haven't seen any document regarding the same, but I will confirm this internally and get back to you.

Thanks,

You can refer to the code within the SDK itself — that’s the best and most reliable reference we have.

Configuration: pdk_c665x_2_0_16/packages/ti/boot/ibl/src/util/iblConfig/src/device.c
Page Read + ECC enable: pdk_c665x_2_0_16/packages/ti/boot/ibl/src/hw/nands/emif25/nandemif25.c
ECC correction math: pdk_c665x_2_0_16/packages/ti/boot/ibl/src/hw/nands/emif25/nandemif25.c
Top-level read loop: pdk_c665x_2_0_16/packages/ti/boot/ibl/src/driver/nand/nand.c

Hi Betsy,

I am currently building the IBL from mcsdk_2_01_02_06.
I would like to confirm whether I can refer to the PDK code you pointed out as a reference for ECC-related implementation.

Also, I would like to reference some registers.
Could you please let me know where I can find the official TI documentation for them?

Best regards,
Lee

Please refer the code located at "mcsdk_2_01_01_04\tools\boot_loader\ibl\src\ecc".

The only reference we currently have is the implementation provided within the SDK/MCSDK. Below are the relevant documentation links for your reference:

As mentioned earlier, you may also find the following thread helpful: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1316902/tms320c6657-4bit-ecc-nand-error?,
