[PATCH 1/2] Corrected the sample start address for EMC 14 computers.
The emc14 sample memory start address had been set to 0x94000 and should be 0x20000. --- src/cochran_commander.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/cochran_commander.c b/src/cochran_commander.c index 895c859..a1be22f 100644 --- a/src/cochran_commander.c +++ b/src/cochran_commander.c @@ -382,7 +382,7 @@ cochran_commander_get_config (const unsigned char *model, { conf->model = COCHRAN_MODEL_EMC_14; conf->log_size = 512; - conf->sample_memory_start_address = 0x94000; + conf->sample_memory_start_address = 0x20000; conf->dive_num_ptr = 0x56; conf->dive_count_ptr = 0xD2; conf->dive_count_endian = COCHRAN_LE_TYPE; -- 1.9.3
Memory end address is now defined. It may not be accurate for model which have a memory capacity disabled. Fixed sample start address for EMC-14.
