S32DS compile problem

825414066 — Fri, 04 Dec 2020 01:51:10 GMT

I have a bootloader project base on the Ymodem protocol used for S32R274, so I need my app project can generate a bin file, then I change my app project configure like this:

But when I finish compiled, I found my core z4 and z7b bin file is too large, its almost 1G, my computer can not edit with that.

by the way, the z7a bin file is normal size.

I guess it cause by my bin file have some SRAM content to record, so that result the address span of flash and SRAM is too large, then cause the large bin file.

I dont need the SRAM content, I dont know how to eliminate that from project setting, It anyone could help me please.

Regards

Hello,

yes, the binary will fill the whole free memory and S32R274 has a quite large memory.

Move over using binary for bootloader source doesnt makes much sense. There are no addresses, nothing.

Ideally you would use S-record for bootloader.

best regards,

Peter
