S32DS debug can't erasing flash

[suomichen]

                 

Hello,

     I have a question regarding the S32DS debugger for the MPC5742.

     I used 0x00800000-0x00803fff for dflash.but when i download a new elf file to the chip,i find the flash area did't erased.

    the following is the debugger i configured.

    

   I don't change the advanced options 

         

Best regards,

Suomi

Hi Suomi, 

can you please share your elf file or srec file? I'll test it on my board.

Hi Jiri ,

Thanks for report. I can reproduce it and you are right. It looks like that cflash algorithm doesn't touch dflash area and left data as it is. I'm not sure if it is kind of "feature". I'll do more investigation. 

I use workaround - you can use alternative algorithm located in [YOUR_S32DS_Install]\eclipse\plugins\com.pemicro.debug.gdbjtag.ppc_1.7.2.201709281658\win32\gdi\P&E

Flashing itself fails because of missing data. But dflash is erased. After that you can remove Alternative Algorithm. I'll let you know if I find better way how to erase dflash area. It looks like that in S32DS is not such option.

hi 

I can't find the option in S32 v1.1 and S32 v2.0

Hi, 

S32DS has no version 2.0 for Power PC. Your S32DS version is probably for ARM architecture.
