Hi,

I'm using CYUSBS234 USB-serial development kit (CY7C65211A), and trying to use command line tool to download the configuration file. However, I downloaded default_CY7C65215-32LTXI.cyusb by mistake.

After downloading the file, three devices are listed in the device manager, but  I cannot select the device on Configuration Utility anymore.

Can anyone tell me how to restore it? Thanks.

Hi SSDK,

 can you please try the below command?

 fwDownload.exe -c default_CY7C65211-24LTXI.cyusb -vid 0x4b4 -pid 0x002 -sn 1

lets consider if in your case device is detecting vendor mfg. then check vid and pid.

as per image you shared use below command 

fwDownload.exe -c default_CY7C65211-24LTXI.cyusb -vid 0x4b4 -pid 0x005 -sn 1

Hi, 

In addition to above information,  below is how I setupt my board:

1. SW1 and SW2 both at 2-3. (I'm using bus power mode.)
2. J29 is at 2-3.
3. J7 is on.  J4 and J8 are removed.
4. J17, J19, J21, J20 are configured as SCB (UART)
5. J18, J22 are at 1-2.

With the configuration above, there are 4 devices with VID 0x04B4 listed in the device manager, and I still cannot see any device is detected in Configuration Utility.

I found a Linux configuration tool in here (not sure it should work on CY7C65211A or not). However, in this tool,  CyGetSiliconID()  and CyReadDeviceConfig() functions are stuck in libusb_control_transfer()/libusb in waiting state for the complet event to occur.

Please tell me how to make CYUSBS234 configurable again. Thank you.

Here is the the devices list in the device manager (win 10):

I noticed a post about reprograming when manufacturing mode disabled. Unfortunately, I can't see any serial port enumerated in the device manager when the device connected. Could you please tell me if there is a way to fix it?

Hi SSDK ,

you can try with the Windows command line if it is enumerated as CY7C65215 in your system.

just check the vid and pid in the device manager and take the below folder and flash the CY7C65211 Configuration file .

please follow below KBA article for how to flash.

Hi Varun,

I tried to use the command line utility tool from the link. However,  it shows "Failed to program the configuration with serial number". Could you please tell me what may cause this problem?

The Configuration Utility cannot detect my device either. I'm not sure they are related. 

Thanks.
