Hello,
I am new to embedded programming and have been presented with a TMS320C5515 to program on.
I have been going through documentation and got to the "C55x Programmers Guide" written/published in 2001. I tried to do the assembly tutorial at the beginning and cannot get the project to compile correctly. It was difficult to follow the steps becaus the CCS interface shown in the figures are outdated. I received the following errors when trying to compile the example:
Severity and Description Path Resource Location Creation Time Id[E0300] 'x' is not defined in this source file tutor tutor.asm line 3 1337888769012 2144[E0300] 'y' is not defined in this source file tutor tutor.asm line 3 1337888769012 2145[E9999] Illegal directive or mnemonic tutor tutor.asm line 1 1337888769012 2142[E9999] Illegal operand tutor tutor.asm line 4 1337888769012 2146[E9999] Illegal operand tutor tutor.asm line 5 1337888769012 2147[E9999] Illegal token in column 1 tutor tutor.asm line 1 1337888769012 2143[E9999] Invalid section name specification tutor tutor.asm line 6 1337888769012 2149[E9999] Syntax Error tutor tutor.asm line 29 1337888769012 2150[E9999] Unexpected trailing operand(s) tutor tutor.asm line 6 1337888769012 2148
8372.tutor.asm
Thanks in advance for any input, and God Bless!

Dozier,
Please indent the "add" line under Step3b to the left to column #0. I suppose you are using CCSv4. Please make sure you choose TMS320C5515 as the Device Variant in the CCS build tab - you can reach this by right clicking on the project and choosing Build Options.
You will also need to make sure that the "Codegen outputs algebraic assembly" option is unchecked under the "Runtime Model Options" as your assembly source file uses mnemonic instructions.
If there is a mix of algebraic and mnemonic assembly source files, then you can set this option (check it) for the project Build Options and uncheck it for individual mnemonic source files under Properties - which you can reach by right clicking on those files under the project.
A good way to start would be to use the configuration setup of examples of the C5515 Low Power Chip Support Library (which you can download here. You could also get started with the setup from the C5515 audio filter demo which is available here. These projects will have all the correct settings for the C5515 eZdsp including command linker files which you will need if you want to run your test code on the device on the eZdsp. Once you have these compiling, you can replace the source file with your source file. Just remember that the CSL examples, is setup to run in the C environment, so your test function should be called "_main". I have made these changes to your file and attached it here 1602.tutor_mod.asm.
To run this test code on the device, memory placement of the vars and table sections will also have to be properly defined in the command linker file. I have changed the "table" section to "tables". Please see the attached command linker file here. 6562.C5515.cmd
Hope this helps.
Regards,
Sunil D. Kamath
