Does TMS570LC4357 support little-endian?

Other Parts Discussed in Thread: RM57L843, TMS570LC4357

I have some questions. I am going to migrate RM57L843 to TMS570LC4357. I show that TMS570LC4357 supports big-endian at TI web site.

1. Does it mean we can use little-endian also as the same RM57L843?

2. Is it solved to triple WR problem for accessing EMIF?

Hi Sunny,

The TMS570LC4357 MCU is a big-endian system. You cannot change the endianness of the CPU or the memory from within an application. You can use the same source code as RM57L843. You do need to recompile this source code with the correct endianness chosen as one of the compiler options.

Regards, Sunil

Dear Sunil,

Thanks Sunil.

OK, I see. I have another question.

Is there byte endianness or bit endianness?

If I connect special DPRAM device using a little-endian, do I have to cross connection of D0~D15 signal pins reversely?

Can I use the same PCB for RM57L843?

Thanks in advance.

Sunny
