Programming problem with 0.4 over UART

GoogleCodeExporter commented 9 years ago

I am using version 0.3 without issue, I just tried 0.4 but I am getting an 
error.

I've attached a file that fails, although I don't think it's related to the 
file at all. I also notice that stm32flash writes the whole memory even if the 
HEX file is sparse.

The command is:

./stm32flash -b 115200 -i 26,32,-25,25:-26,-32,-25,25 -w copro.hex /dev/ttyAMA0

Here is the console output:

Thanks for the report, and especially for providing a test case. Does it fail 
also if you convert the hex file to a binary?

In stm32.c you can simply change

    /* must be 32bit aligned */
-   if (address & 0x3 || len & 0x3) {
to
    /* must be 32bit aligned */
+   if (address & 0x3) {

because after that you anyway pad data to needed size
