I do not want to use NANO FPGA board and do not want to remove R51, R46, R52, R48 and R56 resistors from the interface board.
In theory, it is possible with firmware_v1r08.
Is it working?
Would you please send the basic steps for firmware_v1r08?

P.S.: I am using XP SP2 and no driver issues with Cypress USB or NANO board USB. Both seem to work perfectly. But since I did not remove the resistors, it fails in register test.
On the other hand, it can read the register values in the PC GUI program. How could it possible?
If you are using firmware_v1r08, the SPI interface will be configured via the Cypress chip. You don’t need the FPGA for that. Download the latest firmware from link below:
Follow the Chapter 4 in the MyriadRF Manual Guide. You can skip the Chapter 4.3 because you do not use FPGA. Download document from link below:
I updated the firmware successfully by first doing the steps in
“4.2.3. Downloading firmware to the not empty EEPROM”
and then steps in
“4.2.2. Downloading firmware to the empty EEPROM”.
But, this time I can not read any register value by means of PC GUI and “register test” stuck.
On power up, EEPROM should be uploaded to the Cypress USB chip because J5 is short.
I can see the “Cypress USB Generic Driver (3.4.7.000)” in the device manager.
Although everything seem to be OK, I can not read any register and can not perform the register test.
I tried with both NANO FPGA board is stacked and not stacked. I did not program it.
I think, it is related with the “communications settings” in the GUI.
There are only two COM ports, COM1 and COM2.
It is in the COM radio button, either gives 0x00 in “register test”.
It is in the USB radio button, either stuck in “register test”.
I am using XP SP2 over VMware. My basic OS is Win7 64-bit.
As for GUI, use always COM setting and select correct COM port. You can find the dedicated COM port for board in “device manager”. If GUI does not see it:
1-) HKEY_LOCAL_MACHINE\Software\Microsoft\Driver Signing was already 0x00
2-) In my computer KB2506014 had already been updated since 31 Aug 2011.
3-) I downloaded and installed EasyBCD 2.2. and on its “Advanced Tab”, I checked;
“Allow use of unsigned drivers on 64-Bit Windows”
Then, “Save Settings” and reboot my computer.
Now I can see the “Cypress USB Generic Driver (3.4.7.000)” under the USB devices in Device Manager.
In its properties, it is seen as; Port_#0002.Hub_#0004
But there is a yellow “!” mark on it, because of warning; “… no digital signature, code 52”.
GUI sees it as COM Port 4 but “register test” reads all 0x00. I never set the radio button to USB side and CyControl.exe utility from Cypress does not see any USB.
I tried your procedure many times;
Close GUI
Unplug USB cable from the board
Plug the USB cable to the board
Run GUI.
But it never worked.
How about the +5V external power. I tried to give power after USB cable, before USB cable. But nothing changed.
I also tried all the SPI speeds but no response.
