JTAG-Booster for AMD ÉlanSC520

8 JTAGEL5d.doc

Erase Time : 1.1 sec

Programming Time : 121.2 sec

(1) The initialization file JTAGEL5.INI was found in the current directory.

(2) The target identification line of the initialization file is printed here.

(3) The resulting I/O-address of the parallel port is printed here.

(4) A JTAG-Booster is found on the parallel port

(5) The JTAG chain is analyzed. There may be several parts in the JTAG chain.

The chain is analyzed and all parts except the AMD ÉlanSC520 are

switched to bypass mode.

Please note: The current revision of the AMD ÉlanSC520 has a silicon bug

with the JTAG identification register. As a result of that bug, the contents of

the identification register is shifted out infinitely. If there are other devices in

the JTAG chain, the AMD ÉlanSC520 must be the first part in the chain

(nearest to TDI). Otherwise the JTAG-Booster does not work.

(6) The length of all instruction registers in the JTAG chain are added.

(7) The position of the AMD ÉlanSC520 in the JTAG chain is checked.

(8) The position of the JTAG instruction register of the AMD ÉlanSC520 is

checked

(9) One Flash-EPROM AMD 29F040 selected with chip select BOOTCS# is

found.

(10) In this example two blocks must be erased.
