Spansion S29GS128 over BCM96358

Excellent. You seem to have the 32KB version.

Please test this version: www.embededdcomputers.net/BC_TEST3.zip

This is to check to make sure it selects the correct chip, and also the correct bus. I have a suspicion your device is actually 8-bit, not 16-bit. Which may also fix the writing problem.
 
all FF with the very last one
can I try to write, cause maybe is really all FF in the flash
 
I tried again flashing just the CFE part, and after 1 error it write ok later.
The router now do something, turns on all leds and auto restart every 2 minutes, so it near to work properly.

Okay, so the software and avr firmware works for your flash. However, what is happening is the device you are using is constantly resetting itself. Bascially the CPU is trying to run the code on the flash, and thus, will crash (causing the write error) and will reset, repeating the process.

So one thing you can try, is to you try and "lock" or "halt" the CPU prior to programming.

Try this console command: Ejctrl(0x10000)

Then try to do a FULL flash write. I would also recommend you uncheck "verify data", so that it will try and write all the data at once without trying to put the device into read mode.
 
Hello,
I´m going to try, while try I want to ask you two questions:
1. can I write the command in the script this way:
Code: 
# Script file for Huawei HG556a
 
MyDevice = "NHuawei HG556a"    #Name of device
JTAG.MemoryAddress(0x0)
JTAG.MemoryType("RAM")
JTAG.MemorySize(0x1f00000)
CFGMEM = JTAG.MemoryInit()
JTAG.MemoryAddress(0x1f000000)
JTAG.MemoryType("CFI")
CFGFLASH = JTAG.MemoryInit()
Ejctrl(0x10000)

and second question is if I don´t use the trst of the jtag will help with the resets issue?

thx in davance and best regards
