Hi,
I have a strange behaviour regarding memory access between my user application
and the driver i have developed I'd like to get some clarification on.
The development is all used on or1k arch.
On the application side, I have a buffer declared as:
#define PACKET_SIZE 256
volatile uint8_t __at

Hi,
Can I presume that using errno with RTEMS does not work? To me I'm baffled that
a RTEMS_SUCCESSFULL value must be returned in order to retain the errno value.

Hi Chris,
I am pretty sure the driver is working fine yes. I had this

Hi,
In my RTEMS driver I set and return error value by following macro:
rtems_set_errno_and_return_minus_one(EALREADY);
But in my rtems app when I print the error out by:
fd = open(RTEMS_SYSFLASH_DEVICE_NAME, O_RDWR);
if(fd < 0) {
printk("Couldn't Open device (%d:%d:%s).", fd, errno, strerror
Hi,
I put some debug macos in my driver and when building the rtems, i get failure
in telned. Any idea why?
RTEMS version 4.10.99 from git some time from May.
My configuration: ../rtems/configure --target=or1k-rtems4.11
--enable-rtemsbsp=or1k-bb --enable-test=samples
--prefix=/home/indy/devel/
ked the BSP at boot
time. So all is good. However, I'm unsure if this is the way to do it. Properly
i mean. Is there any doc on this or have I missed it?

C
CONFIGURE_APPLICATION_NEEDS_MY_DRIVER
AAC_MYDRIVER_DRIVER,
#endif
...
And then in the application:
#define CONFIGURE_APPLICATION_NEEDS_MY_DRIVER
Is this correct?

Hi,
I'm trying to initialize (get up) my driver for a or1k target. I reused the the

(except the hello msg in Init fiunction. Does anyone know why?
I updated the file as shown below. At this point I am only interested
