Part Number: TMS570LC4357
Other Parts Discussed in Thread: HALCOGEN

您好！

我最近在用TMS570LC4357这款芯片的开发板，HALCoGen自动生成的CMD文件是FLASH运行的，每次调试都需要擦写FLASH，太慢了。

我需要像C2000的DSP那样（TI提供了RAM模式的CMD），可以在RAM模式下调试，由于没有找到570的现成的RAM 模式CMD，所以我自行修改了FLASH模式的CMD，虽然编译不报错，但是也没有实现在RAM上调试这个目标。

修改前的CMD如下：

//起始地址是0000 0000，FLASH的首地址

MEMORY

{

VECTORS (X) : origin=0x00000000 length=0x00000020

FLASH0 (RX) : origin=0x00000020 length=0x001FFFE0

FLASH1 (RX) : origin=0x00200000 length=0x00200000

STACKS (RW) : origin=0x08000000 length=0x00001500

RAM (RW) : origin=0x08001500 length=0x0007EB00

}

SECTIONS

{

.intvecs : {} > VECTORS

.text align(32) : {} > FLASH0 | FLASH1

.const align(32) : {} > FLASH0 | FLASH1

.cinit align(32) : {} > FLASH0 | FLASH1

.pinit align(32) : {} > FLASH0 | FLASH1

.bss : {} > RAM

.data : {} > RAM

.sysmem : {} > RAM

}

修改后的CMD如下：

//起始地址是0800 0000，RAM的首地址

MEMORY

{

VECTORS (X) : origin=0x08000000 length=0x00000020

FLASH0 (RX) : origin=0x08000020 length=0x00008000

FLASH1 (RX) : origin=0x08008020 length=0x00009000

STACKS (RW) : origin=0x08011020 length=0x00009000

RAM (RW) : origin=0x0801A020 length=0x00064FE0

}

SECTIONS

{

.intvecs : {} > VECTORS

.text align(32) : {} > FLASH0 | FLASH1

.const align(32) : {} > FLASH0 | FLASH1

.cinit align(32) : {} > FLASH0 | FLASH1

.pinit align(32) : {} > FLASH0 | FLASH1

.bss : {} > RAM

.data : {} > RAM

.sysmem : {} > RAM

/*.TI.ramfunc : {} > RAM*/

}

请帮忙指导下，570是否支持RAM模式debug，如果支持，应该如何正确修改CMD？如何将FLASH和RAM的地址映射上呢？

谢谢！

Hello!

I have been using the development board of TMS570LC4357 recently, and the CMD file automatically generated by HALCoGen is for debugging on the FLASH mode. Every time I debug, I need to rewrite FLASH, which is too slow.

I need a CMD file for debugging on the RAM mode. However, I did not find it, so I'm trying to modify the FLASH mode CMD file. Although there were no compilation errors, I did not achieve the goal of debugging on the RAM mode.

The CMD before modification is as follows:

//The FLASH starting address is 0x0000 0000

MEMORY

{

VECTORS (X) : origin=0x00000000 length=0x00000020

FLASH0 (RX) : origin=0x00000020 length=0x001FFFE0

FLASH1 (RX) : origin=0x00200000 length=0x00200000

STACKS (RW) : origin=0x08000000 length=0x00001500

RAM (RW) : origin=0x08001500 length=0x0007EB00

}

SECTIONS

{

.intvecs : {} > VECTORS

.text align(32) : {} > FLASH0 | FLASH1

.const align(32) : {} > FLASH0 | FLASH1

.cinit align(32) : {} > FLASH0 | FLASH1

.pinit align(32) : {} > FLASH0 | FLASH1

.bss : {} > RAM

.data : {} > RAM

.sysmem : {} > RAM

}

The CMD after modification is as follows:

//The RAM starting address is 0x0800 0000

MEMORY

{

VECTORS (X) : origin=0x08000000 length=0x00000020

FLASH0 (RX) : origin=0x08000020 length=0x00008000

FLASH1 (RX) : origin=0x08008020 length=0x00009000

STACKS (RW) : origin=0x08011020 length=0x00009000

RAM (RW) : origin=0x0801A020 length=0x00064FE0

}

SECTIONS

{

.intvecs : {} > VECTORS

.text align(32) : {} > FLASH0 | FLASH1

.const align(32) : {} > FLASH0 | FLASH1

.cinit align(32) : {} > FLASH0 | FLASH1

.pinit align(32) : {} > FLASH0 | FLASH1

.bss : {} > RAM

.data : {} > RAM

.sysmem : {} > RAM

/*.TI.ramfunc : {} > RAM*/

}

Could you please provide guidance on whether the 570 supports RAM mode debugging? If so, how should I modify the CMD correctly? How to map the addresses of FLASH and RAM?

Thanks!

Hi Jiangbo,

The TMS570 and RM4x/5x MCUs do allow you to remap Flash and on-chip SRAM, so what you are looking for is supported. This way you can develop smaller code routines to test specific functions and features without having to reprogram the Flash for every code change you make.

The changes in linker cmd file:

1: Memory:

change stack to a memory range in Flash
