STM Studio and elf file from GNU ARM eabi 4.8

Hi all,

I have issue with importing variables in to STM Studio 3.3. Import shows me only few variables (usually only uint8_t type), rest variables of different types (uint16_t, uint32_t ..) are not in list. Elf file compiled by ARM GNU eabi 4.8 2014q2 from Coocox IDE same as map file shows address of all variables. I can read them to stm studio, but I have to fill variable address and size manually and after some modification in program I have to do it again.

So I think that there is some noncompatibility between elf file and import method.

Does anyone knows what to do to produce compatible elf file with stm studio?

Elf file decoded header (part of it - variables are there)

Hello,

The STMStudio was not validated with such elf file, so most probably the file is badly parsed. May you please post a little example (elf file only) for us to investigate ? Thank you !

Meanwhile, if your linker provides such kind of functionality, you might try to change the format for debugging information, just in case they are better parsed by the STMStudio v3.3.

Best regards

Hi SC,

I tried to modify format of elf file, but I was not successful. I attached some sample elf file.

Thanks for your interest,

Regards,

Hello,

Thank you for the elf file, it effectively shows a syntax not managed by STMStudio v3.3 and not faced with other supported compilers. Please find in attachment a beta version of a v3.4 fixing this (zip file with 2 jar files to extract in ''Program Files''\STMicroelectronics\STMStudio).

Note that this version has not been validated, however modifications are localized.

I hope this will help

Best regards
