Summary of change:
'''Subpage of AfreshTiny''' '''Firmware Releases''' Most recent release : [http://www.vems.hu/download/round/round_2009-04-30.zip round_2009-04-30.zip] Old releases : http://www.vems.hu/download/round/ * [http://www.vems.hu/download/round/round_2007-04-25.zip round_2007-04-25.zip] ** some useful linear wideband voltage output modes require this, see AfreshTiny/VoltageOutput '''Firmware upgrade does not change the factory configuration''' saved in EEPROM. Even if we add new variables to firmware, we keep the old variables in place. ---- '''Firmware upgrade''' * verify that your COM-port works. Settings: 19200,8n1. Try in MegaTune (or possibly in TerminalProgram: SManmxc, expect something like "comm works") * unzip the archive. You will see: ** round.chex firmware file ** roundloader.exe native win32 binary ** "UploadFirmware.bat" You need to edit this, and adjust to your COMx port: *** eg. change COM3 => COM2 (whatever applies): *** roundloader.exe -p COM3 -s 19200 -f round.chex -c write *** if you see C:\tmp\STABLE1_0\minrtest\round.chex change it to round.chex * make sure '''supply connection is stable'''. Supply must not drop out during firmware upgrade. If that accident happens, "SSSSSS" flooding would be needed to get it back to life again. '''Use a good supply, with stable connection''' * start "UploadFirmware.bat" from a "run -> cmd" shell, not by clicking on it so you see the output (success or error). Firmware upgrade takes appr 25 seconds. The following image shows how to look a successfull firmware upload: http://www.vems.hu/files/Display/Round/success_upload.JPG ---- '''Supported windows versions''' Roundloader.exe seems to work on win32 systems from w98 to XP (and likely newer), if COM-port is otherwise working: * XP with pl2303 USB-RS232 adapter cable from WebShop: success * Successfully upgraded/verified firmware with roundloader on WinXp sp2, notebook with USB/RS232 adapter. Seems fine. (MembersPage/GergelyLezsak) * Successfully used roundloader to upload new firmware. Used on Dell D810 laptop on COM1. (Stefcross) ---- '''Supported Linux method ... Oldschool firmware upgrade method''' - for experts only prog.pl Works (similar to BootLoader) with new (included in the zip) prog.pl version (PERL and serialport module required, NOT included). '''Prog.pl only recommended on linux, or if roundloader does not work for some reason'''. Ask for a linux roundloader native executable if you need it. ---- '''Recover from interrupted firmware upgrade''' Normally, this should NOT be necessary. For round, if firmware upgrade is interrupted, the serial loopback method will NOT work. Either it will stay in bootloader by itself, or only 'S' flooding will work: send a file from TerminalProgram full of "SSSSSSSSSSSSSSSSSSSSSSSSSSSSS" (make it 6..30kbyte to be convenient, because it sends appr 2kbyte/sec) in 19200,8n1 while the round is powered up; than any standard firmware upgrade tool like roundloader should be able to communicate and upgrade firmware ---- '''Revert to default config''' (wbo2, EGT, etc...) '''Avoid this !''' Only do it if variables seem to be badly misconfigured. * '''before doing it''' take not of calibration variables: wbo2_pump_pwzero, wbo2_nernstdc_target, egt_offset, egt_cal, * write 255 into wbo2_pump_pw_zero, save (burn to eeprom) and reboot. This procedure should not normally be necessary. It reverts to wbo2_pump_pw_zero=0x65 and egt_offset=0xC0 so you might want to recalibrate: * adjust pump_pw_zero (best values vary from 0x62..0x68 for a certain controller) * and egt_offset (easy, looking at the temp, especially if the sensor is room-temp or an alligator clip is used on the EGT terminals)
