K64 Linker 64-bit Alignment

I need some help creating a 64-bit aligned srecord. Everything is fine except for two records created from ewl, __init_array_start and __init_array_end. They create two back-to-back 32-bit records. Unfortunately FTFE will not allow me to write these records independently. Is there a way to make it create one record or put them on 64-bit boundaries?

Hi Michael,

I recommend that you use the SRecord utility (see CRC Checksum Generation with ‘SRecord’ Tools for GNU and Eclipse | MCU on Eclipse ) which has several options, e.g. −Output_Block_Alignment.

I hope this helps,

Erich

Thinking more about the request about aligning S19 file records: I have received a lot of questions/requests around that topic recently. So maybe better I write up a quick article how I have solved that on my side?

Hi Michael,

this article hopefully helps:

Hi Erich,

Do you know where I can put srec_cat.exe to that I don't have to specify a path? I'm using CW10.6 and GCC on Windows 7.

Thanks,

-Mike

Hi Mike,

for KDS, the 'current directory' is the output folder (e.g. DEBUG or FLASH). For CW I'm not sure: try to use the output folder where the ELF/binary file is as base, or the project root folder.
