EFM-02 USB interface program mode change

alexb · Sep 2nd 2015, 12:00pm

Hi!
May be someone know how to change USB3.0 interface program mode of EFM-02 dev.board?
On the Cypress explorer demo board the RAM boot loader VID 0x04B4 PID 0x00F3, on EFM-02 I saw VID 0x10F8 PID 0xC581.
How can I turn off EEPROM load and set to RAM firmware load?
My software provides USB firmware load every time when board is turn on.

Hello Alex,

I understand that you want to replace the Cypress FX3 firmware. The EFM-02 board is
meant to be customized by Xilinx Spartan-6 FPGA bitstreams, but it is not meant
to be customized by replacing the Cypress FX3 firmware. The Cypress FX3 PMODE[2:0]
pins are set to make the Cypress FX3 boot from I2C EEPROM, and there is no official way
to replace the EEPROM firmware. For a significant volume of boards CESYS may offer a
solution for you. Please contact sales@cesys.com in this case.

Hi Manfred,
Yes, you are understand correctly.

FX3 has a pmodes:

F00 Sync ADMux (16-bit)
F01 Async ADMux (16-bit)
F11 USB boot I need this.
F0F Async SRAM (16-bit)
F1F I2C, On Failure, USB Boot is Enabled
1FF I2C only You used this.
0F1 SPI, On Failure, USB Boot is Enabled

Where I can find pull up resistors on the board for changing mode?

Hello Alex,

I have sent the information where to find the Cypress PMODE[0:2] pull-up resistors
to you via E-mail. Of course, re-soldering the resistors on the EFM-02 board will
nullify the board's warranty. Hope this helps.

Hi Manfred,

Could you also send me information where to find the Cypress PMODE[0:2] pull-up resistors?

Thanks

Dear Burak,

you have both EFM-02 and EFM-03 devices. Do you need the Cypress PMODE[0:2] information
for EFM-02 only, or for both EFM-02 and EFM-03? If you need this information for EFM-03,
I have to request it from my hardware colleagues first, so that will take a little bit longer.

Hi Manfred,

For now I need that information for EFM-02.

Hi Manfred,

Could you send me information where I can find in EFM-02 and EFM-03 modules the Cypress PMODE[0:2] pull-up resistors?

Best regards

Dear Robef,

I have sent the information for EFM-02B to you via E-mail. For EFM-03, this information
still has to be assembled. This will take some time.
