Dear openocd developers,
to add support of TMS320VC5502, mentioned in tcl/target/omap5912.cfg, following
code in src/jtag/core.c should be fixed:
~~~~
#define JTAG_IRLEN_MAX 60
...
void jtag_tap_init(struct jtag_tap *tap)
{
unsigned ir_len_bits;
unsigned ir_len_bytes;
/* if we're autoprobing, cope with potentially huge ir_length */
ir_len_bits = tap->ir_length ? : JTAG_IRLEN_MAX;
ir_len_bytes = DIV_ROUND_UP(ir_len_bits, 8);
tap->expected = calloc(1, ir_len_bytes);
tap->expected_mask = calloc(1, ir_len_bytes);
tap->cur_instr = malloc(ir_len_bytes);
/** @todo cope better with ir_length bigger than 32 bits */
if (ir_len_bits > 32)
ir_len_bits = 32;
...
~~~~
Is it a major design issue of openocd or it could be fixed in an easier way?
Thanks,
Andrey
