Yes, I would think that "RAM_START" actually should be "SRAM_START". Did you were able to get rid of the error?

Thanks Kristin, yes, I must have read that tutorial at least a hundred times :) It's a very important reference when getting started with SES. I noticed that Raphael's reference to section placement is "RAM_START" while the tutorial correctly refers to SRAM_START. I got my section info from the SDK example ARMGCC folder (.ld) file and used exactly that as it should be I guess, origin 0x1b000 for FLASH and 0x20001870 for SRAM.

For setting up the project, did you follow this blog post?

Raphael found a solution to the "Stopped by vector catch" problem in an older version the blog (here):

Found a solution for the "Stopped by vector catch" problem. Apparently I was using the wrong flash and RAM starts

Setting the Section Placement Macros to FLASH_START=0x1b000 RAM_START=0x20001f00 based on the linker file included in the armgcc directory worked for me.

Note that I was using S130 with PCA10028 and SDK v11-alpha2. I did not change the flash_placement.xml. I believe the start values for flash and RAM there should remain what they are and not be the same as the section placement macros, i.e. not factor in the SoftDevice. Correct me if I am wrong, but that is what I used and it worked for me.
