Hi,

I think so.

Now I have to write a IAP bootload code to Flash memory first via the JTAG, and then update code via RS232 or USB.

BTW, I found it is difficult to program the STR9's flash via FlashLINK in the CAPS, it is need to try many times for a success. My PC is P4 2.6G with windows XP.

Hi Guys,

STR912FW4?X6 device:

Do you know if ST have any plans for a simple in circuit bootloader app that allows flash programming using a PC's RS232 or USB connecting to the STR9 Rs232 or USB ?

The ST CAPS utility requires special hardware/cables.

Philips have LPC2000 flash utility, Atmel has SamBa etc.

I would like our product to be field upgradable with minimum effort.

Our distributors do not have the skill or knowledge to use JTAG and take the lid off the product for flash upgrades.

Maybe I have to write my own ?

Thanks.

Hi STARM

Has the IAP software been posted yet? I couldn't see anything on the forum or the ST Microcontrollers website.

If its available, can you point me to it please. If not, is it still planned? Do you know timescales?

Thanks,

Andy

Hi All,

We are really sorry for this delay for releasing the software.

Finally we have alpha version of the bootloader using the USB , this is called also DFU: Device Firmware Upgrade.

Attached in the zip package you could find the hex file for the bootloader DFU firmware (DFU.hex) + the PC software applet & driver + a sample image (pintoggle) to flash using the bootloader.

Unfortunately, a detailed user manual is still not ready, so I will try to summuarize the needed steps to test the demo.

For testing the demo , you will need to have the STR9-eval board + the CAPS v2.1 utility and the Flash Link JTAG tool for loading the bootloader image and doing a boot bank remapping.

Please find in the following the needed steps:

1- using CAPS tool, change the boot bank in order to boot from BANK1 (secondary 32K flash).

2- using CAPS tool, flash the DFU.hex code in BANK1 at address 0x0.

3- install the PC software applet (setup.exe).

4- power-on the STR9-eval board and plug the USB cable (make sure that JP9 is in the position 2-3), the PC should recognize the usb device and will ask you for driver installation (you will find it in the install folder of the PC applet application).

5- launch the ''DfuSe demonstration'' applet.

6- click on ''Choose'' to load the pintoggle.dfu file to load into the STR9 main flash (pintoggle.dfu is generated from pintoggle.hex uisng the DfuSe file manager utility).

7- click on ''Upgrade'' to load the image.

8- click on ''Leave DFU mode'' to leave DFU and launch the pintoggle demo, you may also launch the pintoggle demo by pressing reset and the ujoystick button then releasing the reset while keeping the button pressed for some time.

Note that the source files for the DFU will be released soon with a complete package (including the user manual).

Sorry again for the inconvenience.

Best Regards,

STARM
