Hi,
I have been running FreeRTOS on NXP's ARMs for a couple of years and for several reasons I'm now considering switching to Luminary micros.
This may not be the best forum to ask, but I though this forum hosts quite a bit of knowledge regarding Luminary microcontrollers.
By any chances, are they out there free C/C++ compilers for Luminary MCUs? If so, do they have any limitations?...

Hi,
I'm trying to access each entry contained in the root folder of a microSD card of 512Mb.
After successfully opening the root folder, ls_getNext fails checking the FAT type of the card. Apparently the only types supported are FAT12 and FAT16.
I can insure the card is FAT16 though... any idea on how to get this to work?.

I thought I would also say that I tried to add the following code and it still fails:
xSemaphoreGiveFromISR(mySemaphore, &dummy);
if(pdTRUE == dummy)
{
portYIELD_FROM_ISR();
}.

Hi,
I have added a tick hook that counts ticks and give a semaphore periodically using xSemaphoreGiveFromISR.
A task waits on this semaphore using xSemaphoreTake and the maximum delay (portMAX_DELAY).
I have an LED that shows when the semaphore is given and an LED showing when the semaphore is taken.
The semaphore is given consistently from the ISR (the ISR LED blinks). You would expect...

Hi,
Sorry if this post appears twice, my first attempt seems to have failed.
I need to write that piece of code that is generic enough that it allows giving a semaphore from the context of either an ISR or a task. Since an ISR must use xSemaphoreGiveFromISR to give semaphores, is it possible to use xSemaphoreGiveFromISR in the context of a task?
If so, any cons with doing this?
Jean.

Hi,
thanks for providing such a library, it's been a while since I've been looking at something similar.
Could you provide more information regarding the library's footprint and execution time for whatever processor you've tested this it on?
Also, do you have any plans to move away from the vector library? Vectors tend not to be supported that well by embedded systems...
Do you have any...

Yepee! got it! OpenOCD 0.1.0 works right of the install, after the lpc2129 target cfg file is converted to the Windows format...
I'm now ready to run freeRTOS!

Yes, everything (openOCD, eclipse, GDB...) is running on the windows host.

Hi,
Thanks for the detailed answer. The board I'm running does not have an LED I can toggle... Shame. I have an LCD, a CAN bus port, serial port, but no LED... But rev 2 will for have one for sure!
I tried to telnet openOCD on localhost but it does not look like any port (neither 3333 or 4444) are open. I double checked this running netstat -abov. No port open at 4444 or 3333.
This is...
