Hi,
I'm currently trying to write an ROP chain as an example on how the
Jiminy-board might be abused. During that research I noticed that RIOT
can only accept ASCII chars, but not just any arbitrary hex value. The
isr_pipeline uses chars, which on the avr platform, default to signed
chars. Therefore RIOTs behaviour becomes, at least in my opinion, kind
of undefined when sending e.g. 0xff.
Is there a specific reason for using signed chars instead of unsigned
ones?
Best regards,
Steffen
