1. Sure, but JTAG is used (as standard) for testing only (with commands 
BYPASS, IDCODE, EXTEST etc.).
2. I asked about Flash memory programming - not using SRAM as a program 
memory.
3. If you want to load some code to SRAM memory you should use special 
commands (codes) for switching TAP into "SRAM load mode" (name of this mode 
is my own, it is not possible to find them in official docs ;-)).
