Please use the flasher command line option info to get the desired information. Example for netX 90 is shown below.

enter inside a windows command line:

> lua5.1.exe cli_flash.lua info

enter number of the connected interface to the netX 90

look for the following information inside the output of the flasher

Board info:
Bus 1: Serial Flash
        Unit 0: SQI
        Unit 1: SPI0_APP
        Unit 2: SPI1_APP
        Unit 3: SPI2_APP
Bus 2: Internal Flash
        Unit 0: IFLASH0
        Unit 1: IFLASH1
        Unit 2: IFLASH2
        Unit 3: IFLASH01

use this information for the parameter -b and -u

use for the internal flash always -cs 0.

The final netX 90 version will not have any support to program other pages of the internal flash than the main flash. This is cs 0.

Please see also the following examples of flashing a file:
A file can be written in "flash" mode. The offset in flash is 0 by default, which corresponds to the beginning of the memory area. This can be changed with the option "-s".

Examples:
Flash the file "firmware.bin" into memory on bus 1, unit 0, chip select 0 and offset 0:

lua5.1.exe cli_flash.lua flash -b 1 -u 0 -cs 0 firmware.bin

Flash the file "firmware.bin" into memory on bus 1, unit 0, chip select 0 and offset 0x1000:

lua5.1.exe cli_flash.lua flash -b 1 -u 0 -cs 0 -s 0x1000 firmware.bin

Write to internal flash:

parameter cs is always 0 for netX 90 to address the internal flash memory
COM area: at offset 0x3000

lua5.1.exe cli_flash.lua flash -b 2 -u 3 -cs 0 -s 0x3000 firmware_com.bin

APP range: at offset 0x0000lua5.1.exe cli_flash.lua flash -b 2 -u 2 -cs 0 -s 0x0000 firmware_app.bin
