Hi, I am trying to update the fash of STM32F407 by using the Flash Loader Demo V1.3, but it does not seem to communicate to my processor. I used this program to flash my STM32F10x series, but I don't know if it will work for F4xx series. Could someone tell me what do I need to update the flash through RS232 interface. Thanks

Try v2.4.0 should support the F2, and the F4 is very similar.

Hi Clive,

Is there any user manual for this new version. I did assumed its baud rate is the same as older version (57600), Parity = Even, Flow Control = OFF. It doesn't seem to work for me. I did tried several different baud rate but it acts the same. I can see the processor's RX1 activity, but the TX1 just goes high and stay high. By the way, the processor is in the right mode (BOOT0 = 1, BOOT 1 = 0) when power is applied. If you know anything else for me to try, please help. Thanks

It should auto-baud, ie it measures the 0x7F pattern to compute bit timing. As I recall it should also support USART3, and USB connectivity, there is a manual and it covers additional pin states. The USART needs to go to something like a MAX232 to interface to RS232 level signals.

Yes, I have an external RS232 transceiver. I moved to UART3 and it works fine. So I guess the new chip does not support UART1.

USART1 is supposed to work, I haven't experimented with it, but :

''USART3_RX (PB11), USART3_RX (PC11), CAN2_RX (PB05), OTG_FS_DM (PA11) and OTG_FS_DP (PA12) pins must be kept at a high or low level during the detection phase.''
