Error during flash firmware for ST67W61

Hi everyone,

 

Currently, I'm trying to re-flash firmware for ST67W61 module via UART without host ( use USB TTL), and I got the issue in below:

The Hardware that I setup in below:
1. USB-TTL connect to ST67W61 via TX/RX pin

2. PIN BOOT, ENABLE is to pull-up with 3.3V via SW1 (BOOT) and SW2 (ENABLE), see the picture in attachment

3. The sequence that I did : press and hold SW2 (chip ENABLE), press and release SW1 (BOOT), then release SW2.

Do everyone has experience please help me to check whether my HW and sequence already correct or not?

 

Thank you very much!

Hello,

 

By default the BOOT is pull down (33k) and the CHIP_EN is pull up (already inside the module, no need to add external pull up). So on the your schematic, the switch SW1 should be linked to 3.3V and to enter the boot mode, you have to follow this sequence:

- Press SW1 to keep BOOT at 3.3V.

- Push and release SW2: make a "reset".

- Release SW1.

Then the module is in BOOT mode and you should be able to flash the module.

Hope it will help,

Regards,

Damien.

Hi @DHUBA.1 ,

 

Thanks for your response!

1. I'm setup the schematic like this, please help me to review.

2. Could you help me to check the timming and shoud I add this command after which steps?

QConn_Flash\QConn_Flash_Cmd.exe --port COM5 --config NCP_Binaries\mission_t01_flash_prog_cfg.ini --efuse=NCP_Binaries\efusedata.bin

Step 1: Press SW1 to keep BOOT at 3.3V.

Step 2: Push and release SW2: make a "reset".

Step 3: Release SW1.

 

Regards,

Giang

Hi Giang,

 

I think I gave you a wrong information, there's no pull up on the CHIP_EN signal inside the module but the pull up is managed by the host (STM32). Can you detailed a little bit more your schematic ? how do you interface the ST67 (UART / SPI) ? Which host are you using ?

If you only want to to flash the module and control manually the CHIP_EN and the UART (no Host connected), you indeed need external Pull_up on CHIP_EN and Pull_down on the BOOT (see image in attachment).

In that Hardware configuration, your timing is correct.

Regards,

 

Damien.

Hi @DHUBA.1 

Background is that I want to use a host (STM32F7) to communicate with ST67W61 via SPI (follow T01 architecture).
follow topic: https://community.st.com/t5/interface-and-connectivity-ics/stm32-host-with-st67w611-wifi-ble/m-p/886532/highlight/true#M12366 
I understand that I have to re-flash for ST67W61 module before start with any applicaiton in host like P2P client, ...

and now, I'm trying to flash fimrware for ST67W61, I used UART TTL module, connect to ST67W61 via TX/RX pins, and the BOOT pin, ENABLE pin I setup following your recommend.

after setup, I use this command to start for flashing:
QConn_Flash\QConn_Flash_Cmd.exe --port COM5 --config NCP_Binaries\mission_t01_flash_prog_cfg.ini --efuse=NCP_Binaries\efusedata.bin

Unfurtunately, I'm still got the same problem that I mentioned at the begin of this topic.

Do you have any suggestion?

Regards,

Giang

If I understood your problem correctly, unfortunately I'm also seeing the same issue after installing t01 the first time. I'm unable to re-flash the ST67 again and for me the device seems bricked. I tried it on several boards and see the same issue. I have no problem re-flashing on boards with t02 installed the first time. It allows reflashing of t02 again and again. However, the moment I flash t01 successfully, the device gets bricked.

My workaround was to do a full chip erase before reflash

QConn_Flash\QConn_Flash_Cmd.exe --port COM38 --erase --whole_chip

After which I was able to flash either binary on ST67s

Hi @Nkh ,

Thanks for your information!

for my case, this is the first time I try to flash for ST67W61.
could you share some experience like HW setup, sequency for press and release button BOOT and ENABLE?

@DHUBA.1 already shared about the schematic for BOOT, ENABLE, also sequecen. but I just get the handshake success, still not flash successfully yet.

 

Thanks,

Giang

Not sure about the timings as I also do it manually via a switch. Here's an example of the start of a successful output

One other important thing if you are using your own custom board... your serial port must be able to support 2000000 (2M) baud rate. The flashing only works at that speed.
