A google search for this error indicates an issue with gdb when pathnames have a space. This does not seem to be the case here as both projects are in the same Projects folder.

In regard to warning; ''not enough working area available(requested 8192, free 8144)''

The following post explains that this is expected because flash algorithm uses 48 bytes.

I found that the gdb run command was not complete, my cut and paste error. Now updated to the following;

target remote localhost:3333 symbol-file main.out monitor soft_reset_halt monitor flash erase_sector 0 0 31 monitor flash write_image main.bin 0x08000000 thbreak main cont I no longer get the original error and gdb seems to keep running. Looks like I may have a program error as it goes to the hardfault handler with gdb console;Info:    server.c:78 add_connection(): accepting 'gdb' connection from 0 Warning: gdb_server.c:416 gdb_get_packet_inner(): acknowledgment received, but no packet pending User:    target.c:1838 handle_soft_reset_halt_command(): requesting target halt and executing a soft reset User:    gdb_server.c:574 gdb_output(): erased sectors 0 through 31 on flash bank 0 in 1.029602s Warning: target.c:853 target_alloc_working_area(): not enough working area available(requested 8192, free 8144) User:    gdb_server.c:574 gdb_output(): wrote 11262 byte from file main.bin in 1.451803s (7.575440 kb/s) Error:   cortex_swjdp.c:222 swjdp_transaction_endcheck(): SWJ-DP STICKY ERROR Error:   cortex_swjdp.c:236 swjdp_transaction_endcheck(): dcb_dhcsr 0x30003, nvic_shcsr 0x20000, nvic_cfsr 0x1, nvic_bfar 0xe000edf8 Error:   cortex_swjdp.c:222 swjdp_transaction_endcheck(): SWJ-DP STICKY ERROR Error:   cortex_swjdp.c:236 swjdp_transaction_endcheck(): dcb_dhcsr 0x30003, nvic_shcsr 0x20000, nvic_cfsr 0x1, nvic_bfar 0xe000edf8 Warning: cortex_swjdp.c:703 ahbap_read_buf_u32(): Block read error address 0xfffffff0, count 0x1 Error:   gdb_server.c:1024 gdb_error(): unexpected error -107 Now need to decipher the above error....
