We are using RTEMS 4.10.2 + EPICS R3.14.12.4 for the beatnik and mvme2307 BSPs.<br>
<br>
What I've noticed is that the boot files created for the beatnik BSP are more than twice the size of the boot files for the mvme2307. In some cases, the boot file is too large for the "user download buffer" so the tftpGet fails on startup.<br>
<br>
I realize that these two BSPs use different PPC CPUs (7400 vs. 604), but I wonder why the great disparity in compiled file size.<br>

I don't think the instruction set makes a big difference. I would look at the ELF file to figure out how the sections are placed and how big the are, e.g. objdump -h.<br>
