36 this is the release of the firmware version 1.0

it is considered as complete, fully functional and as we know bug free.

changelog since version 0.5:
- stand-alone mode fully working (writing to the spi flash and fpga configuration during start-up)
- added some more visual guidiance using the bi-color LED. we flash now the LED for all commands using one or the other memory slot in the spi flash, this is start-up configuration, writing to the spi flash (mem:data) and delete of a fpga configuration (mem:del)
- old externel usbtmc driver confirmed to be working with linux 2.6.33		 nussgipfel 5364d 18h /gecko3/trunk/GECKO3COM/gecko3com-fw/firmware/include/firmware_version.h
35 immediate test version. stand-alone spi flash bug is away. was a bus conflict, because we modifie the spi bus pins at two different code locations.

just a backup at the moment. needs more testing before a stable release.		 nussgipfel 5390d 18h /gecko3/trunk/GECKO3COM/gecko3com-fw/firmware/include/firmware_version.h
33 fixed in the bit file header analyse function. it was not possible to handle bit files (configure fpga, store into spi flash) when using USB 1.1 conections.

disabled the debug define in the firmware Makefile

removed the chipscope file from the GECKO3COM_simple project to get the logic utilisation of our core only.		 nussgipfel 5404d 12h /gecko3/trunk/GECKO3COM/gecko3com-fw/firmware/include/firmware_version.h
28 switched to work on the v1 production GECKO3main. the timing is a big issue
with the prototype system. the cabeling and the possibly bad influence of the
prototype board layout makes it impossible to run this core in sync with the
host transfers.

out transfer is fully working. always in sync with the transfers and reads all
tmc headers correctly.

abort handling in the core works as well. there were some fixes needed in the
firmware, not all IN FIFO buffer where flushed.

a lot of work was done for the IN transfer (fpga to pc). the in transfer
handling in GECKO3COM_simple_test.vhd is finished.

the GECKO3COM_simple_datapath/fsm is finished.

there is still an issue left but I think the problem is in the gpif_com
module. for long IN transfers, we still not receive the correct number of bytes.

it works great for all sort of short transfers.


Here I present a time measurement to show the achieved message throughput:
(Response message was 1 byte, total with header and align bytes was 16 byte)

time for i in {0..100000}; do cat /dev/usbtmc1 > /dev/null; done

real 5m45.706s
user 0m27.498s
sys 4m52.676s

This shows that we can read data from the fpga with a rate up to 290 Hz		 nussgipfel 5418d 14h /gecko3/trunk/GECKO3COM/gecko3com-fw/firmware/include/firmware_version.h
21 system is fully working and tested with big files over 4 Gbyte. there were some smaller bugs and glitches which caused
sometimes a deadlock. they are fixed now.

one was because the fx2 reads the done pin sometimes wrong during a long data
transfer. I don't now if this is because of crosstalk on my prototyping system or fpga internal weakness.
a simple debouncing (read again after 40 ms) did the trick.

changed firmware version to 0.5rc0, basically all features targeted for 0.5 are done.		 nussgipfel 5447d 14h /gecko3/trunk/GECKO3COM/gecko3com-fw/firmware/include/firmware_version.h
16 release candidate 3: 0.4rc3

fixed a bug in the get_capabilities function. was fixed before but it was back again...

removed one file from the build process, that shouldn't be in the subversion.		 nussgipfel 5474d 19h /gecko3/trunk/GECKO3COM/gecko3com-fw/firmware/include/firmware_version.h
15 this is the release of version 0.4rc2

we provide now the downloadable *.iic file of the current version in the repository at the convinient place
"gecko3com-fw/firmware/"		 nussgipfel 5487d 19h /gecko3/trunk/GECKO3COM/gecko3com-fw/firmware/include/firmware_version.h
9 First commit to the OC svn.

This is the release candidate for the GECKO3COM firmware version 0.4.

Included are all sources, scripts and helper tools.

Implemented functionality to this firmware version:
- FW upgrade through USB DFU class
- works as a USB TMC device (test and measurement class)
- handles all mandatory IEEE488 and SCPI commands
- fpga can be configured through USB
- two different fpga configuration files can be downloaded the the onboard memory
- loads one of these configuration files during power on

next step is to implement the transparent data communication between the USB host and the FPGA		 nussgipfel 5519d 19h /gecko3/trunk/GECKO3COM/gecko3com-fw/firmware/include/firmware_version.h
