Problem about the WinROM 3.1 software

Other Parts Discussed in Thread: TUSB7340

Hello Sir,

We are using TUSB7340 chip in our project. We want to configure EEPROM device of this chip and for this purpose we get WinROM 3.1 software from TI E2E community. I connected TUSB7340 demo board to PC without any problem. However, when I write any single address of the EEPROM and turn off/on the WinROM 3.1 software, the data of all addresses of the EEPROM becomes the value that I write before for single address. For instance, I write 0x55 for the fifth address of the EEPROM. Then, I turn off and turn on the WinROM 3.1 software. After that, the data of all addresses of the EEPROM seems 0x55. It means that, I can not write any specific address of the EEPROM. I can only write one value to all of the addresses . Could you help us to solve this problem?

Best Regards

Hello,
We've never had issues with this software, can you use another system?
Are you using an TUSB7340's EVM? If not, can you share your schematics?
Regards

Hello Elias,

We are using TUSB7340 EVM. WinROM 3.1 software recognised EEPROM after the connection process. After that, we wrote 8 bit data to any single address. There is no problem until this process. However, when we turned off and then turned on the WinROM 3.1 software, the data of all addresses of the EEPROM seem same and it is equal to data that we wrote to any single address before.

We populated pull up resistors for the I2C interface of the EEPROM on the TUSB7340 EVM. Could we need to do some other rework on TUSB7340 EVM ?

Best Regards

Hello,
No reworks are needed.
Was the EEPROM already installed on the EVM?
Can you try with another system? Uninstall and re-install the software.
It is probably a faulty eeprom.

Hello,

Could you send me a copy of WinROM 3.1 for TUSB7340, I need it to configure the eeprom according to my need.

Thanks!
