LAUNCHXL2-TMS57012: TMS570LS12xx or RM46

Hi Wayne,

1. Why is it with RM46x rather than TMS570LS12xx?

I think they by mistake delivered Lauchpad with RM46x instead of TMS570LS12xx.

However, both the controllers are pin to pin compatible with each other.

As you can see, the hardware schematic is same for both of them. Just we can place any of the controller on launchpad.

2. Can they program codes onto this RM46x MCU using TMS570LS12xx codes and CCS target configuration setting?

No, we can't program both of them with same configurations. We should choose corresponding controller in the CCS configurations.

And also, there is a endian difference between these two controllers.

We should make sure this in our application code.

RM46x is a little endian device.

TMS570LS12x is a big endian device.

3. They used to use TMS5700714APGEQQ1R, can they program its codes onto this RM46x MCU directly? We are asking this because they were trying to buy EVM kits for TMS5700714APGEQQ1R, and ti.com shows LAUNCHXL2-TMS57012 is the development kit for TMS570LS0714-S (TMS5700714APGEQQ1R).

TMS570LS07x is also a big endian device.

So, if you are trying program the TMS570LS07x code into the RM46x then some type castings might go wrong. So, we should consider this and should modify the code accordingly.
