VER5.26a compiled with cgtools 5.1.12 (CCS3.1) released 07/17/07 OFFICIAL RELEASE
1. VC40XXE/VC44XXE only:
use new FPGA Revision R07 to improve ethernet performance
VER5.26 compiled with cgtools 5.1.12 (CCS3.1) released 07/05/07 OFFICIAL RELEASE
1. internal
2. improved telnet_out task -> Faster output.
3. added IMPORTANT Note in Readme.txt -> Wait 30 seconds before booting camera during OS update.
KNOWN ISSUES:
DNS works only with first DNS server !!! IP file entry example: "NS1: 192.168.26.1"
VER5.25.13 compiled with cgtools 5.1.12 (CCS3.1) released 06/27/07 NEW FEATURE RELEASE
1. added DNS support -> for instance $ping www.vision-components.com can be now used on the camera (use: saving images on remote server, automatic OS updates in the future). New functions: "gethostbyname()" and "gethostbyaddr()"
2. changed sensor optimization for VC4X38E and VC4X68E
VER5.25.12 compiled with cgtools 5.1.12 (CCS3.1) released 06/13/07 BUG FIX RELEASE
1. optimized VC4X38/58/65/66/68E for FPGA release R06
VER5.25.11b compiled with cgtools 5.1.12 (CCS3.1) released 06/04/07 BUG FIX RELEASE
1. fixed reset of config: only pressing ESC key should lead to reset to default IP
-> any key was resetting the IP address before (autoexec stopped only with "ESC").
VER5.25.11a compiled with cgtools 5.1.12 (CCS3.1) released 05/30/07 BUG FIX RELEASE
1. VC4XXXE only: use compatible mode for accessing SD cards formatted with old driver -> change data format back to little endian
2. VC4XXXE only: use Release R06 of FPGA bit files
3. internal
VER5.25.11 compiled with cgtools 5.1.12 (CCS3.1) released 05/24/07 BUG FIX RELEASE
1. VC4468E improved picture quality / sensorid 0x52 supported
2. raw input for telnet
3. removed wait for key in debug mode (loading of relocatable code)
4. use new SDCARD driver (improved speed) -> now reading 60kB up to 500 kB / sec. Writing 800 kB/s up to 2MB/s Speed vary depending on SD card.
VER5.25.10 compiled with cgtools 5.1.12 (CCS3.1) released 05/05/07 BUG FIX RELEASE
1. VC2065EC: fixed init of rgbo mem -> fixed checksum bug initialising color pages, that could have caused system to crash.
2. FTP server: fixed device full and write error distinction -> now destinction between "write error" and "Flash full".
3. increased VC_MAX_EVENTS from 32 to 644.
4. VCRT.H: added io_fstatus and io_status -> now prototypes in VCRT.h io_status corresponds to io_fstatus for the stdin.
5. VCRT.H: added TCP/IP error codes
6. VC4008E,VC4016E,VC4018E/B only: added CPLD VERSION 5 support (CPU CPLD version) -> this fixes cancel_capture_rq() bug that took one more image after cancel_request() in HW trigger mode.
7. use CACHE_LINE_SIZE aligned memory allocation for C64XX ->from 64 to 128 bytes. Better performance.
8. added debug switchable output for loader -> Shell command "$dbg 1" "$dbg 0" toggels the debug switch. With DEBUG_SWITCH = ON , offsets are displayed at the next program start. This debug message also includes the "relocateable code" message, that was previously displayed at each execution of a relocatable program. This makes it now possible to debug relocatable code using an Emulator (see new emulator instructions in the public download area -> HW manuals.
9. fixed raw output for telnet device -> output of binary data using IO control via Telnet is now done correctly (no CR = CR +LF conversion).
10. shell: added "dbg" command to change sysvar DEBUG_SWITCH per command -> see 8.
11. C64XX: optimized flash timings for 90ns
12. image timestamps are using now U64 type instead of long (see VCRT.H) -> This ensures the unix date format (seconds since 1.1.1900) of the image timestamp (introduced in 5.23) can be displayed correctly.
13. added VC4438E support
VER5.25.9 compiled with cgtools 5.1.12 (CCS3.1) released 03/22/07 BUG FIX RELEASE
1. TCP/IP: fixed VCRT_getsockopt()
2. support for both old and new head CPLD rev 0x80 for VC4018E -> New Camera OS works with all hardware (also with old Sensor boards).
3. internal
4. FTP server: fixed memory leak in list/dir command -> Calling the list/ dir command when using FTP was allocating but not releasing memory before.
5. FTP server: improved upload speed: Now 2-3 times faster uploads with FTP!
VER5.25.8 compiled with cgtools 6.0.10 (CCS3.3) released 03/02/07 BUG FIX RELEASE
1. use new compiler from CCS 3.3 for libs and kernel
2. fixed slow write in MediaCard filesystem
3. support for both old and new head CPLD rev 0x20 for VC4038E -> from now on, old cameras without encoder interface can be updated with new VCRT OS versions.
However: Do not upload old VCRT OS Versions prior to 5.25-8 on new cameras!
4. internal
5. improved timing for TCP/IP stack (5.25.8a)
VER5.25.7 compiled with cgtools 5.1.11 (CCS3.1) released 02/22/07 BUG FIX RELEASE
1. fixed echo negotiation for telnet clients -> now Telnet clients can be used without echo. Now all shell commands can be executed using a standard Telnet client - Only expetion: Program upload using "$lo" is not supported.
2. added ioctl for telnet device to enable raw output
3. Latest PC library versions used for generating this operating system.
VER5.25.6 compiled with cgtools 5.1.11 (CCS3.1) released 02/08/07 BUG FIX RELEASE
1. fixed DHCP client - bug was introduced in VCRT5.24.29 (DHCP worked only once)
2. added VC4472E suppport
3. minor enhancements in SD card performance
4. internal
VER5.25.5 compiled with cgtools 5.1.11 (CCS3.1) released 01/26/07 NEW FEATURE RELEASE
1. added VC boot logo -> Vision Components Logo now displayed at start- up
2. support for both old and new head CPLD rev 0x40 for VC4X65E
3. added display of VCRT version and hardware model on Video output at start-up.
4. fixed telnet takeover message when using VCP recovery unsing VCNET
5. do gratious ARP at boot time to force ARP cache updates -> conflicting old arp entries are deleted automatically in the PC arp table in order to allow connecting to a different camera hardware with the same IP adress of a previously used camera.
6. internal
7. fixed loader strcpy of last command
VER5.25.4 compiled with cgtools 5.1.11 (CCS3.1) released 01/12/07 NEW FEATURE RELEASE
1. automatic connect of events (needs new vcrt4.lib !!!) ->the functions event_connect_to_task() and event_disconnect() are no longer required in parallel task.
2. new exec3() allows tuning of priority and timeslice per function call
3. fixed parsing of ip file (IP file is ignored if specified IP address invalid- an empty #IP file could cause IP address 0.0.0.0 previously)
4. added .txt as a valid ASCII extension (now automatically changed to *.001 during upload)
5. file descriptor of a pipe shows now size of pipe
6. the system variable DISP_ACTIVE on VC4XXX Hardware allows now disable of display DMA -> this allows higher calculation performance in case the video output is not required! command "disp -a 0/1" allows to set this from shell
7. added reload of compressed executeables - loader version 5.25.4 (in case a program was calling itself again and compressed to *.cex).
8. print to stderr if file is relocatebale (now printed to "DEBUG info - see above).
9. Shell command "$kl" shows now debug logs
10. removed shell commands dmp and jt command - added unix command shortcuts cp (copy files), ls (dir), rm (delete file) , ps (= procs = print task list)...
11. update5 allows now update of older VC4XXX hardware without encoder support (see above)
12. internal
13. internal
14. internal
VER5.25.3 compiled with cgtools 5.1.10 (CCS3.1) released 12/05/06 NEW FEATURE RELEASE
1. Added KEEPALIVE to FTP and TELNET Server:
Every tcp connection sends now keepalive packets to test the link every minute.
If link is down for more than 100 seconds the tcp connection will be closed !!!
2. Added telnet session TAKE OVER feature:
Telnet currently deals only with one shell connection. Now its possible to
take over a running telnet connection and drop the old one.
3. changed VC4X58E settings for new FPGA Rev 103
4. internal
5. shell command "ex" disconnects telnet connection
VER5.25.2 compiled with cgtools 5.1.10 (CCS3.1) released 11/30/06 BUG FIX RELEASE
1. CAUTION!!! (old programs may have to me changed)
VC4002E,VC4008E,VC4016E,VC4018E/B only: reversed polarity of trig_inp signal !!! trig_inp now conforms to specification (e.g. TRIGINP_POS() triggers on rising edge).
2. fixed bug in serial driver close that could prevent characters from beeing sent.
3. TCP/IP: reenable directed broadcast again - was disabled to prevent smurf attacks
VER5.25.1 compiled with cgtools 5.1.10 (CCS3.1) released 11/24/06 TEST ONLY RELEASE
1. changed VC4X58E settings
2. VC20XX only: fixed init of powfail variable
