hi guy's

Anyone can help me out how I can remove a FW from ESMT F59L4G81A

Which device I need and Software :


CPU STi 7105, 450MHz, 800 DMIPS
DRAM 256 MB
Flash 256 / 512 MB

the ESMT Flash is a F59L4G81A where has a JTAG pin on side with 10pins

Looks like NAND flash. I am not sure if the "JTAG" port is for the NAND flash or it is for the CPU. You need to hook up the JTAG first and see if you can "detect" the device (IDCODE).
What is your main purpose for the device?
If the JTAG port is for the CPU, then it is needed to write code to read/write the NAND flash. Nor flash typically does not need to write special code.
