[hpsdr] Compile FX2-fw

[Bill Tracey]

Hi Gerd,

Not sure what the error might be.  The error message is a little 
deceptive, PowerSDR is likely complaining that it does not see Ozy, 
or that the FX2 firmware it is not responding as expected.    When 
you power on PowerSDR do you see the DOS window running initozy11.bat 
run?  Does it appear to succeed -- you may want to try running it by 
hand to see if the FX2 is loading succesfully and if the FPGA is 
loadingf as well.

I do not know why your .hex file is coming up smaller -- the version 
of SDCC I'm using announces itself as:

SDCC : 
mcs51/gbz80/z80/avr/ds390/pic16/pic14/TININative/xa51/ds400/hc08 
2.6.0 #4309 (Jul 28 2006) (MINGW32)

How much smaller is the .hex you're getting?

One thing to watch out for  is the link order of the modules is 
significant -- the link command I'm using is:

sdcc --verbose -L"f:\sdcc\lib" --no-xinit-opt --xram-loc 0x2000 
--xram-size 0x2000 --code-size 0x2000 -Wl -b" USBDESCSEG = 0xE000" 
-o"ozyfw-sdr1k.hex"  ./Initial/src/asm/vectors.rel 
./Initial/src/asm/_startup.rel 
./Initial/src/asm/usb_descriptors_X1.rel 
./Initial/src/lib/delay.rel ./Initial/src/lib/fx2utils.rel 
./Initial/src/lib/i2c.rel ./Initial/src/lib/isr.rel 
./Initial/src/lib/spi.rel ./Initial/src/lib/timer.rel 
./Initial/src/lib/usb_common.rel  ./Initial/src/board_specific.rel 
./Initial/src/eeprom_io.rel ./Initial/src/fpga_load.rel 
./Initial/src/hpsdr_common.rel 
./Initial/src/hpsdr_main.rel  ./Initial/src/sdr1kctl.rel

I don't remember how much of the ordering is significant -- I know 
for sure vectors.rel has to be first.

The latest version of the code is 
at: 
svn://206.216.146.154/svn/repos_sdr_hpsdr/trunk/KD5TFD/Ozy-FX2-SDR1K-Control 
- can't say I've changed it much of late.

Regards,
