Please help me as I'm currently unable to continue development and it was Semtech that recommended to our company that we should switch over to ST microcontrollers because before this we were using TI and also PIC and had no issues with either of those. Also noticed that ST Link utilities sometimes becomes unresponsive for about 10 seconds. Says it's working normal and driver version is 2.1.0.0.Įven after ST Link utility says there is a usb communication error, in device manager, it's still showing up normal. It shows up under 'universal serial bus device' as 'STM32 STLink'. Also in device manager, ST Link V2 shows up normal. Otherwise the laptop runs great, I have no other problems, all my USB ports are working great. Does this sound like normal behavior or is my ST Link V2 broken (it's brand new)? Can I download an older version of ST Link utilities? However, if I try to evaluate arcsin (sin (48pi/11)) 4pi/11, the 89 returns. If I do it in approximate mode, the decimal value is the same (correct) value for all of the three expressions. This is technically correct, but not the solution. My problem is that I have issues connecting to a target but I'm having issues even without the target, so I don't know if the problem is with my target or with the ST Link utility software. The answer should be 4pi/11, however the 89 gives me arcsin (cos (3pi/22)) as an answer in exact mode. I change Mode back to 'connect under reset', and now it is saying the USB communication error again. I click refresh and now it looks all correct again (as stated above). Now it says 'No ST-LINK detected !', I plug ST LINK V2 back in. Next I unplug the ST LINK V2, then click on Refresh. Also under serial number it now says 'Old ST-LINK firmware/ST-LINK already used'. Now it is saying USB Communication Error! I hit refresh, doesn't make a difference. The settings window closes, I open settings again. I change the Mode to normal, the OK button becomes grayed out, so I have no other choice but to hit cancel. I go to Settings, everything looks good, it shows the serial number and FW version V2J29S7. If you are unable to obtain the correct homebrew patches, then download the Applet version of Tinfoil.I'm using Windows 8.1, I plug in ST LINK V2 in USB port, but I do not yet connect the other side to a target. If you install it and Tinfoil will not launch, then you are missing the correct signature patches required to run homebrew titles. If you are unsure which version to get, just download the Self Installer.Īpplet version requires title override / high memory to be ran or it will crash, has slightly worse user experience, and will not auto-update.
