Hi Janne, Thanks for that. In the interim I re-wired our board to reflect the application note and it all works .. yay :-)
I have a question on downloading to the target. I get the following when gdb executes my script: ---------------------------------- output from gdb ---------------------------------------------------- source touchscreen.elf set remoteaddresssize 64 set remotetimeout 999999 target remote localhost:2000 0x0000e000 in _reset_vector__ () monitor erase all Erasing target flash - all... Erased OK Loading section .text, size 0x400 lma 0xe000 load Debug/touchscreen.elf Loading section .data, size 0x2 lma 0xe400 Loading section .vectors, size 0x20 lma 0xffe0 Start address 0xe000, load size 1058 Transfer rate: 1 KB/sec, 211 bytes/write. ---------------------------------------------------------------------------------------------------------- My question relates to the file size and the time it takes to program. According to the above, by object size is 1058 bytes and it looks like the transfer rate is 1Kbit or 211 bytes per second? If so it should take about 5 seconds to load. However it loads in about a second, so either these numbers are wrong or all my object code is not being loaded. Any comments?
