UART boot SDRAM allocation problem on C6747

Other Parts Discussed in Thread: TMS320C6747

Hello I have a problem with UART boot. If my project has a code or const allocated in SDRAM, program is not executed properly after UART boot. If SDRAM contains only variables or tables (which do not have to be initialized by the boot program), all goes ok. Maybe my AISGen settings are improper? I use default settings with all checkboxes unchecked. If so, how can I know how to set them? CCSv3.3, Code generation tools v6.1.5, bootloader type D800K003, UART2 boot Device: TMS320C6747, little endian

Hi Irina, Have you went through these links. Flashing the C6747 EVM http://processors.wiki.ti.com/index.php/Flashing_the_C6747_EVM (This is for the evaluation module, but you may find some relevant information from here) Also, you can try the link for further information. Getting Started Guide for C6747 http://processors.wiki.ti.com/index.php/Getting_Started_Guide_for_C6747 Hope this helps. Best Regards, Ankit Agrawal

Yes you will need to use the AISgen tool to initialize the PLL and SDRAM. The GEL file that comes with the EVM has the settings that you can input to the AISgen tool.
