ARM: printf ITM with RTX RTOS
Hello all,
I am having an issue with using the 'Debug (printf) Window' to
display debugging messages as the code runs. Upon startup I print
simple initialization messages using the printf function which
displays an index(printIndex) or count of the message that is being
printed and the message(msg) itself.
printf("%003u - L: %s\r\n",printIndex++, msg);
Most of these messages are display in the 'Debug (printf) Window'

ARM: nonRTX applicaiton faults after using RTX bootloader (6 Replies)
Hi,
Is there something the RTX does, that then effectively stops a
non-RTX process from running?
I have an old and new bootloader (the old is incumbent on the
machines and I'm forced, for the time being, to use it)
I have two builds of the application one with the same RTX OS
(single thread, looped every 10ms) and a non-RTOS version that runs
the same routine every 10ms, so very nearly identical.
* non-RTX bootloader - RTX application works
* non-RTX bootloader - non-R

ARM: IOSTREAM library issue - COUT doesn't print
Is **iostream** library not supported in Keil? I am using Keil in

Does anyone know about it?

ARM: SD CARD NOT DETECTED BY LPC1768 LANDTIGER BOARD (3 Replies)
Hi, i am working on a project using the lpc1768 on the landtiger
board to accesss some files from the sd card(16GB space-32bit pcm
format), the issue i have is that even after powering the sd(LD3 is
on) and after calling the sd_init() function from the sdcard.c file
the sd card stays undetected.
It is also important to note that the example from cortex3 of sd card
read and write provides the same result (sd card power on but not
detected).

ARM: which eMMC is suppoted by Middleware
Hello,
we want to exchange an SD-card in an existing design by an eMMC
because we expect a higher robustness compared to the SD-Card in a
socket. The read/write bandwidth might also be higher (8 bit
interface instead of 4 bit), but of cource this also depends on the
type of flash, (MLC, SLC, ...) and the integrated controller. I read
that the middleware supports eMMC.
We have not used eMMC in the past and therefor have no real
experience this this type of flash memory so I askey our di

ARM: How to remove unused functions with armclang?
Obviously, the option --freedback for armcc doesn't work. But
setting -flto to compiler controls or linker controls (or checking
the Link-time optimization checkbox) shows this error:
error: use of LTO is disallowed in this variant of ARM
Compiler
And that seems strange since this article is dated 2015 -

- and I'm using Keil 5.24.1 two years later.
Is there another way to do it?

ARM: Accessing structure pointer members (5 Replies)
Hi all,
For some reason, I cannot access the structure members if I use
struct pointers.
eg:
typedef struct
{ int member1;
}structure_t;
structure_t structure, *structure_ptr;
int main()
{ sturcture.member1 = 4; //works structure_ptr -> member1 = 4;
//does not work
return 0;
}
I am using KEIL MDK 5.23 with TM4C123GH6PM. I am using the
debugger to see if the member values are changed or not.
What am I missing?
