Hi,

we just found out that the s-record parser can fail in case of unaligned s-records:

Could you check if this is the reason? Could you compare the content of flash with s-record file when it is loaded by the bootloader?

Regards,

Lukas

@lukaszadrapa @nxp Can you please provide few pointers here?

Flashing via the above procedure was successful, but then after the jump to application, it results is bus fault and hardfault.

When the application alone is flashed directly via debugger, there seems to be no issue and it works.

Hello @lukaszadrapa 

Thanks for the reply .

Here am experimenting with AN12218 - UART bootloader , after loading the Example_app.srec file using java, application is not running successfully.

On attaching debugger on run time seen is getting stuck default ISR (Hard fault). seen PC loaded with 0x1450.
