I have code that is compiled in far mode, and when I try to download the code through JTAG Emulator, Code Composer fail to load the code in the far sections. Please let me know you have any suggestions. Is there some setting that I am missing. In c5416.gel, I set PMST_VAL to 0x00A8u to enable DROM. I am using CCS 2.0 for C5000 series. I am woking with C5416 processors. Using JTAG Emulator form Spectrum Digital (XDS510PP Plus). Thanks in advance. Linda |

Ismail, Thank you for replying. The problem I am having is the code composer quit when the progress bar is halfway without loading the extended section. I does not give any error messages. The extended section can be clearly seen in the map file. I tried to edit the location at far mode section using CCS and it seem to work. CCS just refuse to load code to that memory section. Using the a third party tool, the code loads and runs fine, so we don't think it's the .out file itself. The following is my settings in gel file. Please let me know if you have any other suggestions. Thanks a lot! GEL_XMDef(0, 0x1eu, 1, 0x8000u, 0x7f); GEL_XMOn(); GEL_MapOn(); GEL_MapReset(); GEL_MapAdd(0x80u,0,0x7F80u,1,1); /* DARAM */ GEL_MapAdd(0x08000u,0,0x8000u,1,1); /* External */ GEL_MapAdd(0x28000u,0,0x8000u,1,1); /* SARAM */ GEL_MapAdd(0x38000u,0,0x8000u,1,1); /* SARAM */ GEL_MapAdd(0x0u,1,0x60u,1,1); /* MMRs */ GEL_MapAdd(0x60u,1,0x7FA0u,1,1); /* DARAM */ GEL_MapAdd(0x08000u,1,0x8000u,1,1); /* DARAM */ Linda > -----Original Message----- > From: Ismail Uzun [mailto:] > Sent: Monday, April 14, 2003 1:21 AM > To: 'lindahyang' > Subject: RE: [c54x] Unable to load code to extended memory using JTAG! > Help! > Hi, > > You should define extended memory before loading it.

Ismail- Thanks for your help. We had a few problems, but the main thing turns out to be that CCS hates linker .cmd file page numbers above 1. For example, in the partial C5416 .cmd file example below, using "PAGE 2", "PAGE 3", etc. is sudden death: CCS will stop loading the program midway through its progress bar with no warning message or other indication that it has seen something it doesn't like. Other COFF file loader software has no trouble with this, but CCS does. If we keep everything on PAGE 0/1 but play with the subnames it's Ok. -Jeff MEMORY { /* low memory */ PAGE 0: ISR (RWX): origin = 0f00h length = 100h /* isr_code */ PAGE 0: DARAM (RWIX): origin = 1000h length = 100h /* talker */ /* .bss section, .stack, .sysmem (heap) */ PAGE 1: DATA0 (RW): origin = 1200h length = 2100h /* .text (code) */ PAGE 0: CODE (RWX): origin = 3300h length = 4d00h /* .const, temp_const, bss2, .data, .buffers */ PAGE 1: DATA1 (RW): origin = 08000h length = 07fe0h PAGE 2: EXT0 (RWX): origin = 18000h length = 8000h /* not used */ PAGE 3: EXT0 (RWX): origin = 28000h length = 8000h PAGE 4: EXT0 (RWX): origin = 38000h length = 8000h } Hanzi Yang wrote: > > Ismail, > > Thank you for replying.
