EV2300 and Windows 7
I have got a new PC that came with Windows 7 pro installed and I am having trouble installing the EV2300 drivers. The updater installs, the the second driver will not. Do you have Windows 7 drivers?
If it's 64-bit Win7 you are out of luck at the moment. If it's 32-bit then this should work, although not officially supported for Win7:
Thanks for your reply, I am running 32-bit win7, however when I try to download the file (whilst logged in to E2E) I get the following message:
Is it possible you could e-mail me the file?
I've tried to attach it to this post. Please try and let me know if you can download it and what your results are:
I managed to download the attachment, thank you. However the drivers still do not install correctly (windows times out during driver install) and the EV2300 is not recognised by the evm software.
The first driver 'TI USB Firmware Updater' installed correctly (windows reports 'Ready to use'). I have tried manually extracting the installer contents to install the drivers, but that did not work either.
The bqEVSW reports: "The EV2300 connection could not be initiated". Then "No USB board was detested!"
Does the evm software support the MCC iPort/USB adapter? (http://www.mcc-us.com/MIIC-204-DS.htm) I am sure I read somewhere that MCC were going to be supported by the bqEVSW.
Manually uninstalled all EV2300 drivers, rebooted and then tried again..... it worked! :)
Many thanks for your help.
Also no luck here with Windows7 64-bit. You know I was shopping for a new PC yesterday, and only saw refurbished PCs with XP. All new PCs had Win7 with 64 bit, even if they did not really need the 64-bit version. Seems like 64-bit is the way things are headed, and very quickly. Would really like to see the 64-bit drivers soon.
Do we have a Windows 7 - 64 bit version of ev2300 drivers available now?
If not, when can we expect them?
Thank you, Keith
I have learned that the ev2400 updated communciations interface will be able to support windows 7 64 bit version. This will be available mid 2011.
Here's more background on why EV2300 does not work with 64-bit Windows and also about EV2400:
I tried to get EV2300 running (for bq33100) on win7 64-bit... and it works, drivers seems to install etc. i dont have any evidence for that but for sure it did work.
I dont know what i did, but it had something to do trying to get it running under vmware virtual xp.
First, it didnt work on neither win7 nor vmware. Then it just started to work under win7, but not under vmware.
Today, i tried again.. Does not work in win7, but now it runs under vmware, uh.
EV2400 is now available for purchase. Finding the drivers is proving to be difficult.
Workaround for 64-bit support of EV2300:
Does anybody know for sure exactly which driver(s) I need to install in order that the EV2300 will talk to "EV2200-60" PC Software Utility through it's expected USB UART interface, instead of the only drivers that I have found actually recognising the EV2300 only as an HID in Device Manager? Having got passed the above Win7-64bit driver issue I've tried the different drivers independently on both XP and Win7, with no noticeable difference, it still feels like a new driver issue.
Strangely the EV2300 which I've only ever seen recognised as only an HID does seam to be recognised by "bq SingleStation Tester", "bq Tester ROM Imager" and "bqReadWriteDQ" PC Software utilities installed only on the Win7 PC. Is it possible the firmware in the EV2300's TUSB3410 needs to be swapped for use with "EV2200-60", if so how? These other bits of PC Software were NOT installed on the XP machine, so it shouldn't be the case that any other hidden HID driver supplied with them is getting in the way of the XP test. I even tried installing the TUSB3410 USB-UART driver and disabling the HID driver in Device Manager, with no success. Any ideas?
Solved my own issue, having found this statement on the forum that explains why it won't connect. "The bq2060A will only work with the EV2200." from:-http://e2e.ti.com/support/power_management/battery_management/f/180/t/190264.aspx
It would appear the only Software support for BQ2060-A is for the older EV2200 UART based hardware tool.
