hi!
i do not understand how this code (from target.c) works.
i'm working with a dsp568013.
each memory address holds 16 bits.
when i run "mdh someaddress count" with count over 16, openocd's
output does not match what i would expect. the first 16 words are
displayed in a line with address "someaddress", but the following
readings are displayed on a line labeled "someaddress+32", when i
would expect + 16 (since 16 mem locations where read).
my problem is with this part of the code, which i guess assumes that
mem locations are 8 bit instead of 16, or something else which i don't
understand.
from target.c:handle_md_output:
//------------------------------------------------------------------
//------------------------------------------------------------------
for (unsigned i = 0; i < count; i++)
{
if (i % line_modulo == 0)
{
output_len += snprintf(output + output_len,
sizeof(output) - output_len,
"0x%8.8x: ",
(unsigned)(address + (i*size)));
//The previous line will make each line begin with address,
address+32, address+64, etc, since size=2 and line_modulo = 32/size.
}
uint32_t value = 0;
const uint8_t *value_ptr = buffer + i * size;
switch (size) {
case 4: value = target_buffer_get_u32(target, value_ptr); break;
case 2: value = target_buffer_get_u16(target, value_ptr); break;
case 1: value = *value_ptr;
}
output_len += snprintf(output + output_len,
sizeof(output) - output_len,
value_fmt, value);
if ((i % line_modulo == line_modulo - 1) || (i == count - 1))
{
command_print(cmd_ctx, "%s", output);
output_len = 0;
}
}
//------------------------------------------------------------------
//------------------------------------------------------------------
do i have to configure something to tell openocd that i'm using 16bit memory?
another question: i haven't been able to find a way to make load_image
and verify_image work with my target, any clues?
to implement "resume" for example, i added .resume=my_resume_function
to my target. is there something similar for load_image?
thanks!
