TMS320C6654: How can I get V1.0.0.4 RBL code？

wang Anna

Part Number: TMS320C6654

Hi,

Let me ask a quick question.
I am using 3 kind of C66x DSP: C6655/54/52，and I downloaded the ROM code for C6655/57 in order to understand RBL behavior.

RBL code is available from the following link:

https://software-dl.ti.com/sdoemb/sdoemb_public_sw/rbl/1_0_C6657/index_FDS.html

I'm reading the code because I need to understand spi boot, but some codes seems to have been modified.

For example, please take a look at chipInitStatusReg() function at Gauss.c.

Judging from the actual operation of RBL, chipKickUnlock() and chipKickLock() seems to be removed from this function at present.

I read RBL version from C6655/54 chip，the RBL version is v01.00.00.04.Tue.Dec.06.18:24:48.2011.

How can I get v01.00.00.04 RBL source code?

Best Regards,
AnnaWang

Sorry, the title is wrong. The RBL version number is v01.00.00.04.

Anna Wang,

For Direct ROM boot example, please have a look at this FAQ.

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1171336/faq-tms320c6657-how-to-run-the-direct-spi-boot-example-on-ti-c6657-evm-without-ibl

This example is tested on the C6657 EVM.

For RBL code reference, this is the only link available.

Anna,

Whatever provided in the RBL package at the link-

https://software-dl.ti.com/sdoemb/sdoemb_public_sw/rbl/1_0_C6657/index_FDS.html

is the one for the customer reference. For proprietary reasons, some of the codes are purposefully removed.

Have you tried the direct spi boot example? Does it help you ?

Anna,

As far as I know, It is the common source for C665x series, applicable for C6654 and C6657.

AnnaWang,

I was further answered by the concerned team.

The RBL code is proprietary.

And yes, few codes were purposely removed for security reasons.

Only for C6657 and C6678 devices, RBL code is released to public. Perhaps not the complete code.
