[ECOS] Is it posible to use Nano-X packet on Vmware template (i386)?

[ECOS] Is it posible to use Nano-X packet on Vmware template (i386)?

[Hakan Çakiroglu]

Is it posible to use nano-x server on Vmware template  (i386)???

I know it is possible to use it with ipaq(I am not sure what ipaq is but somebody has ported for it.)

I 'm using vmware template and adding microwindows package to my template. Then I am compiling 

one of the nano-x demos. But I always get the error message "cannot open graphics"

Is anybody tried this before???

[ECOS] Reading serial ports with timeout

[Laurie Gellatly]

Hi All,
On my LPC2212 board I have serial 1 running at 115K baud.
The data coming into the port is CRC checked.
What we've found is that when the micro at the other end of the serial sends
a packet,
(say 60 bytes) about 10% of the time, one of the characters in the data
stream is missed.
I can sniff the line and see the characters are all there, but my
application misses one at random.
The serial port is interrupt driven. We don't use the 16 char FIFO.
Our code does this:

while( iDataItr < L2OVERHEADSIZE-1 )	{ // need more chars
	cyg_io_get_config(ser_handle, CYG_IO_GET_CONFIG_SERIAL_BUFFER_INFO,
&serial_buffer_info, &iLen); // How many available?
	while( (serial_buffer_info.rx_count != 0) && (iDataItr <
L2OVERHEADSIZE-1) ){		// There are some ready and we need them
		cyg_io_read( ser_handle, &ucHeader[iDataItr++], &iNumBytesToRead );
//blocking read 1 char in
		cyg_io_get_config(ser_handle, CYG_IO_GET_CONFIG_SERIAL_BUFFER_INFO,
&serial_buffer_info, &iLen); // How many available now?
	}
	ulTimeNow = cyg_current_time();				// What the time now
	if( (ulTimeNow - ulTimeStart) > iTimeToWait ){		// Has it taken too long to
read them in (timeout)?
		printf( "Error: processRXPacket(): Header timeout!!\n");
		return PROCESSRX_TIMEOUT;
	}
}

Which is basically,
While we have more data to get, get the number of characters ready to be
read.
While there are characters available and we need more
  read the next 1 character and add it to the buffer
 find out how many characters are ready to be read now?
Get the current time
check to see if its been too long to get this data

When I looked at eCos' PPP implementation I see it uses cyg_alarm_xxx and
just blocks on a cyg_io_read
Is that the 'right' way to do this? Can someone see a flaw in the existing
code?

Many thanks			...Laurie:{)

Never tried it, but should be. Look at the components:
CYGPKG_MICROWINDOWS_PC, CYGIMP_MICROWINDOWS_PCSVGA16, and
CYGIMP_MICROWINDOWS_PCVGA.

I am still working on it. There is no conflicts on package and component selection. I dont think it is beacuse of packages. I think it can not start nano-x server. I dont know if nano-x server really start or not. I am still on it. Thank you for your reply. At least it is good to know that nano-x works on vmware. So I can continue working....

RE: [ECOS] Is it posible to use Nano-X packet on Vmware template (i386)?

[Hakan Çakiroglu]

Hi there;

1.situation
I was trying to do the following :


-First build redboot with default settings by using ecosconfig.exe for i386 (working from floopy)
- After that I was building my template (vmware)  (microwindows packet is included) from ecoscofig.exe
 from build library option.
- And I was compiling my demo program (polytest.c) with the help of vmware .ecc 

There was no problem in the building section. 

-After that I am booting my virtual pc (vmware) with redboot 
-And than I am taking my compiled .srec file to booted virtual pc with the command "load a.srec"
-Finally I am giving the command "go" to run the program. 

I was taking error message "cannot open graphics"

I have continued searching.....

I couldnt find anything but I have tried this after;


  2.situation
-I have only changed my template : I have added build complete ecos+microwindows application settings, build microwindows NANOWM and Build microwindows NanoX demos and built it again by selecting build library. 

No problem in built section.

-This time I have sended xx/xx_install/bin/xx.elf to redboot and gived the command "go"
But this time I am taking this output :

Creating System threads
Creating Nano-X server thread
Creating Nano-WM thread
Starting Threads
Starting Nano-X server
Starting Nano-WM
No Video BIOS information at location 0x000A0000
Please use asuitably configured Redboot for bootstrap
Cannot initialise screen


At that position I have two question.

1- In first situation why no threads have started? Is it because of polytest.c ? But it is ok in nanox demos section??? 
2-OK may be it is wrong to compile only polytest.c to see some result but why I am taking this error in the second situation ?? (No Video BIOS information at location 0x000A0000
Please use asuitably configured Redboot for bootstrap
Cannot initialise screen)

I have looked into  /packages/services/gfx/mw/current/src/drivers/scr_ecospcsvga.c
It says: 
............However the video
       BIOS can normally only be called in x86 real mode, not protected mode,
       Currently eCos only runs in protected mode, and has no support for
       briefly switching back into real mode.

Can anyone tell me how to build redboot bootstrap that supports me???

(And I have also tried unchecking OUTPUT TO PC SCREEN and checking switch the display to an alterative video mode. This must be the solution but this time there is no output in my pc screen. )

Can somebody help me????
Thank you...
