Address range problem with a 27c080 device on the S4

[Guest]

Hi,

I am having trouble setting the address range on my S4 for a AMD 27c080 device, The highest address I can set is 00000,1FFFF

Can anyone help?

Hi Andrew,

Please check the available RAM on your S4 by switching on and reading the third line of the display, it is very likely that you only have a 128Kbyte S4. This is a 512Kbyte chip, please contact Dataman if you require a RAM upgrade, you will be able to set a range of up to 7FFFF on a 512Kbyte S4.

Hello Mike,

This device is supported on the latest S4 main library (2.86) available free from our website. Please download this library into your S4 via the serial cable.

Hi,

I have to burn a 1 Mbytes binary file in an 8 Mbit EEPROM, but S4 Dataman only allows range from 00000 to 7FFFF.

Is there any way of burning the binary in the EEPORM by partitioning it (making it two files of 512 Kbytes)?

Hi,

You need to use a file splitting utility to split the file. It is probably possible to find one by simply doing a google search. We are currently looking into creating one specifically for S4 and will post our solution in this forum soon.

Hello.

Once a binary file has been split, can FLASH ROMs which are larger than the S4's memory be written to in 2 stages, or does FLASH need to be written 'all at once'?

I use a 128K S4 and want to flash a 2Mbit Bios chip (AMIC A290021T). I would upgrade the S4 but it's not mine and getting it upgraded would be like getting blood out of a stone!

Cheers for any info

Hi Al,

Certainly, you must do it in two stages, first download and burn the bottom half of the chip, then transfer the second file and specify upper half of the chip on S4. (Burn 00000,1FFFF,C0000 C cursor here and Up/Down)
