What I’ve read tells me that the STR9 is not shipped with pre-programmed flash that would allow programming via UART.
The first programming has to be done through JTAG.
Have you read [AN2475?](http://www.st.com/stonline/products/literature/anp/12951.pdf)
hello denial,
i am using str7 board to upgrade firmware through uart,
i have gone through the doc AN2078, i migrated it from iar workbench 4.1 to 5.1 am not getting any errors as such, i used one example code of uart str7 and i migrated code.
i think i have to make changes in the 71x_init.s, 71x_vect.s and init_table.s files which am not very familiar to work with.
sending file through ymodem protocol is showing that remote device is not responding, when i send the binary file.
please help me in developing this module
Just to be sure, you did the first programming via JTAG?
yes i programmed via jtag
hello can anyone plz help me out in debugging this
