Hi all, I am trying to load one TAP with instruction, and then shift in some data to that TAP. OpenOCD manual says :
— Command: irscan [tap instruction]+ [-endstate tap_state] For each tap listed, loads the instruction register with its associated numeric instruction. (The number of bits in that instruction may be displayed using the scan_chain command.) For other TAPs, a BYPASS instruction is loaded. and — Command: drscan tap [numbits value]+ [-endstate tap_state] Loads the data register of tap with a series of bit fields that specify the entire register. Each field is numbits bits long with a numeric value (hexadecimal encouraged). The return value holds the original value of each of those fields. So, I was basically using irscan with TAP name and command (hex value), and then drscan - with tap name, num bits I want to shift to TAP and the vaule (in hex). However, this constanly hits the assert : if (!active->bypass) assert(active == tap); in driver.c. I discovered that irscan actually did not put all other TAPs to BYPASS mode leaving tap to which my target CPU is attached in the non-bypass mode, and thus preventing me to write to some other TAP. What would be the best way to avoid this ?
