Retargeting

[Nkrause]

Hi, I'm a bit of a newbie to C and embedded programming. I'm using the ARM Crossworks IDE right now and trying to get the HRM_RX example working on my PCA10028 board. I've imported the code and when ever I attempt to compile it, I get the following errors from the retarget.c file.

error: storage size of '__stdout' isn't known

error: storage size of '__stdin' isn't known

From my reading I understand I have to define the size of these two as Crossworks doesn't do it for me, but I'm at a bit of a loss as to how to do that correctly. Any help is appreciated!

Hi Nkrause,

the retarget.c library is simply overwriting the stdio library such as fputc, fgetc with UART command. I'm not sure how to do it with Crosswork, but you can't, you can simply remove retarge.c and replace those commands to print log with direct UART command to send and receive data.
