Problem on bare metal application using SABRE AI and DS-5

falcobapp — Mon, 08 Jul 2013 08:06:42 GMT

Hello,

i just started on working with an i.MX6 Sabre AI platform and want to work bare metal.

Is there anybody who knows the configuration and scripts needed to execute to get DS-5 connected to the board to load the application?

Thanks,

Falco

Please use scripts from the Platform SDK.

Hello Yuri,

thanks for that fast reply!

I already tried to use those scripts, and it looks like i get connected to the target. But when trying to load the application i get the following messages in the debug window:

Stopping running target Freescale - i.MX6 Quad (Generic) on USB:001567 on connection

And here i am not sure how to fix that issue.

Your load address (0x8000) seems me suspicious :

"Failed to write 5.068 bytes to address S:0x00008000"

i.MX6 has following address ranges for applications (Table 2-1. System memory map of the Reference
Manual) :

0090_0000 - 0093_FFFF internal RAM (OCRAM), useful for small applications, since there is no need for DRAM init.

1000_0000 - FFFF_FFFF DRAM

So, please try to rebuild the application using correct link file, or just correct application memory map.

Got the problem solved. The change of the setting in DS-5 eclipse worked when setting up the adress spaces corectly and update the apropriate linker skript and use of debugger-script.

Thanks a lot Yuri!!
