TUSB3210 - Regarding loading firmware from PC

Hello Subash,

In order to download FW from the host PC to the TUSB3210 device, there's a driver (Apploader) that will do it and load FW in the 3210's RAM space. This driver loads the FW by issuing bulk endpoint transfers.  Here’s the location of such driver: http://www.ti.com/litv/zip/sllc160 .

Please let me know if this helped in something.

Best,

Ismael

Hi Ismael,

Thanks for pointing the Apploader.

I had followed the steps as mentioned in the readme of the Apploader, for downloading the firmware from PC, but not successful.

Please let me know, if am I missing something.

Also can you give Us the linux version of this Apploader, else Please provide the source Code, we will port it to Linux version.

I am using windowsXP, below are steps I had followed.

# Install the apploader mentioned in below path  http://www.ti.com/litv/zip/sllc160

# I noticed the inf file is located in below path.

      C:\WINNT\inf\oem11.inf

# Downloaded firmware from below TI site,  http://focus.ti.com/docs/toolsw/folders/print/tusb3210kbdpdk.html

# Placed the kb3210.bin file extracted from above link, renamed as TUSB2136.bin in below path

      C:\WINNT\system32\drivers

# Now, I had did below Jumpers setting in 3210EVM board,

      U3: 2-3 -> Download firmware from PC thro' loading program

      U9: 1-2 -> Power thro' USB cable

      U12: 1-2 -> Self powered.

# Plug USB cable to PC and 3210EVM, D9 blows red light indicates power supply is ON.

# Configured hyperterminal, and tried for keypresses on 3210EVM, there was no response.

Please find the   C:\WINNT\inf\oem11.inf file attached for reference.

Thanks & Regards,

Hi Ismael,

Just for quicker resolution, please let me know if we can have telcon to resolve this issue.

Since, its very critical we can quickly solve this.

Thanks,

Subash,

I’m attaching a new Apploader driver (this one is v2.0 and works for both 32-bit and 64-bit XP/Vista). Run the setup.exe and follow the directions (read the license agreement), by default the driver binaries will be located at C:\Program Files\Texas Instruments Inc\TI USB Apploader Drivers.

If you are going to use XP 32-bit, go to the “x86” directory and modify the INF file with the name of the BIN file included at the “BIN files” directory. Copy the proper BIN file within the “x86” directory.

The problem you are seeing at your end could be related to a BIN file that doesn’t have the proper header information for the TUSB3210 (2136) device.

Please let me know if this apploader works at your end.

Ismael

Hi Ismael,

I had downloaded the bin file from below TI website link, I am not sure whether it has proper

header information. As mentioned, I had placed the bin file renamed as TUSB2136.bin

as expected in x86 directory.

http://focus.ti.com/docs/toolsw/folders/print/tusb3210kbdpdk.html

I still facing issue in loading the firmware using this latest attachment of Apploader driver.

Please let me know, the bin extracted from above link has proper header info and also

how we can would confirm if the firmware is downloaded into RAM?

Please let me know if we can have a telcon this even India time?

Thanks & Regards,

-Subash.

Hi Subash,

Please take a look to the documet I'm attaching to this post. This will guide with the Apploader installation.

In case this doesn't work for you, please answer the following questions:

1. How is your TUSB3210 device DETECTED at device manager (I need the VID, PID info)?

2. Do you have a serial EEPROM connected to the TUSB3210 device?

3. Did you try on a fresh OS installation (with no previous Apploader instances installed)?

Best,

Ismael

Hi Ismael,

Thanks for the document.  Below are my observation:

1. I had followed instruction as documented the Apploader_driver.pdf file, I

don't see USB devices listed in the Device Manager after connecting the USB cable

into PC.This could be because we have EEPROM(24LC128) is attached in 3210EVM near U12 jumper.

2. I had installed Apploader as fresh, after uninsatlling the previous version of Apploader from control panel.

Please also find the screen snapshot after connecting the USB cable to 3210EVM to PC.

Thanks & Regards,

-Subash

Hi Ismael,

As you have suggested I had tried below 2 options but unsuccessful to see PID reported at device manager:

1. Remove EEPROM from TUSB3210 device and try to follow the instruction as mentioned in Apploader document.

I don't see any PID or VID listed at device manager.

2. Did the item 1 experiment in different PC where apploader is not installed. But didn't see PID at device manager.

Please let me know where could be the issue?

Thanks & Regards,

-Subash.

Hi Ismael,

Apart from using Apploader, we also tried in connecting USB device of TUSB3210EVM
to linux machine, to make sure firmware loading from EEPROM happens properly. For
this we had changed the jumper setting of U3 to 1-2.

We see an issue in USB enumeration. Please let us know if the chip itself is
functioning properly, else the default firmware night be faulty.

Below is the error log message:

Hi Subash,

This is just a follow up in order to see if everything is doing good at your end with the new TUSB3210KBD Eval Board.

Thanks and Best Regards,

Ismael

Hi Ismael,

Sorry for late response. We are yet to receive the board, will

update the status with the new TUSB3210 EVM.

Thanks & Regards,

-Subash

Please let me know if you had a chance to test the apploader for the TUSB3210 with your EVM.

Hi Ismael,

We need to get our EVM soon, will let you know once we do the testing.

Meanwhile can you clarify how can we upload firmware into EEPROM. I thing we

have reference as how to upload the firmware into RAM using the Apploader driver that

you provided.

Thanks & Regards,

-Subash

Hi Subash,

You can load FW into the EEPROM using the proper "Burner Utility", in this case the TUSB2136/3210 EEPROM burner will do the work (available at our website). Please, before you attempt to run/install this utility, ensure that no EEPROM is connected to the 3210 device or it is blank. To accomplish this, you must remove the proper jumper to disconnect the EEPROM... After the utility has been installed, then you must place the jumper you removed, this in order to enable the EEPROM and let it ready for burning through the utility...

Let me know if this make sense or if you have additional questions.

Best,

Ismael

Hi Ismael,

Do you have EEPROM "Burner Utility" for Linux? If yes, can you share the source code for the same?

Thanks & Regards,

-Subash

Hello Subash,

There's neither EEPROM burner for Linux nor source code for this app that could be shared...

Best,

Ismael
