S32K311_UDS_Bootloader

[nirmal_masilamani]

Hello,

I am trying to implement UDS bootloader in S32K311, by refering S32K344 examples in below link .

Unified bootloader Demo - NXP Community

Everything working fine, after Transfer data complete, Boot trying write DOWNLOAD STATUS and CRC in gs_stBootInfo structure.

But when accessing this variable address, i am getting harfault error. In linker file also i create exchange_info block. 

But i am not sure, where this memory is initialized.

Hi @nirmal_masilamani 

Please take a look at this thread, I guess that this is the reason:
