RTOS/AM3359: Loading program into internal memory

David Zaucha

Part Number: AM3359

Tool/software: TI-RTOS

I am getting an error during download about a memory location that I don’t expect to be writing to.

The error is:

CortxA8: Trouble Writing Memory Block at 0x402f00f4 on Page 0 of Length 0x7ff0: (Error -1065 @ 0x3D5A) Unable to access device memory. Verify that the memory address is in valid memory. If error persists, confirm configuration, power-cycle board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 6.0.628.1)

CortxA8: File Loader: Verification failed: Target failed to write 0x402F00F4

CortxA8: GEL: File: C:\ti\myproject\projects\Network_AM3359_arm\AM3359_release\Network_AM3359_arm.out: Load failed.

The memory config is

The load map is

Moving this to Code Composer Studio forums to see why the CCS loader is detecting code in memory section that doesn`t appear in the map file.

David,

I would first check what the linker .map file shows - ultimately it will reflect what was exactly generated.

Another detail: check if the MMU is active while you are trying to load code - sometimes it can confuse the debugger.

Rafael

You might be encountering the same issue as CCS/AM3352: CCS 7.1 debugger attempts to load an AM3352 bootloader compiled with the GCC ARM compiler to an incorrect memory address

The problem in that referenced thread was how the GCC ARM linker was creating the ELF program headers, and the fix was to add the GCC linker option option "-z max-page-size=0x400".
