OPENOCD in a large JTAG chain

paoloeth · April 16, 2010, 8:44am

Dear All

We need to work on a JTAG chain made from 65 devices; our target is to program the SAM7 processor which is the first device in the chain ; as you can see in the following description, there is a multiple repetition of only 4 device in the chain after the SAM7

SAM7 (uControllore della EAST): IRLen=3
ALTERA EPM2210 : IRLen = 10
ALTERA EP4SGX230 : IRLen =10
LATTICE ISP1014 : IRLen = 8
ATMEL AT90CAN32 : IRLen = 4
ALTERA EPM2210 : IRLen = 10
ALTERA EP4SGX230 : IRLen =10
LATTICE ISP1014 : IRLen = 8
ATMEL AT90CAN32 : IRLen = 4
ALTERA EPM2210 : IRLen = 10
ALTERA EP4SGX230 : IRLen =10

…

ATMEL AT90CAN32 : IRLen = 4

We already managed to use OPENOCD in a JTAG chain made from only 5 devices using the following JTAG chain description section:

…

jtag newtap auto0 tap -irlen 4 -ircapture 1 -irmask 0x0f -expected-id 0x0958103f

jtag newtap auto1 tap -irlen 8 -ircapture 1 -irmask 0x03 -expected-id 0x00145043

jtag newtap auto2 tap -irlen 10 -ircapture 1 -irmask 0x3 -expected-id 0x024090dd

jtag newtap auto3 tap -irlen 10 -ircapture 1 -irmask 0x3 -expected-id 0x020a40dd

jtag newtap $_CHIPNAME cpu -irlen 4 -ircapture 1 -irmask 0x0f -expected-id $_CPUTAPID

…

but we encounter some problems when we rise to 9 the number of devices in the chain so when we add the next 4 devices and use the following new chain description in the .cfg file

jtag newtap auto0 tap -irlen 4 -ircapture 1 -irmask 0x0f -expected-id 0x0958103f

jtag newtap auto1 tap -irlen 8 -ircapture 1 -irmask 0x03 -expected-id 0x00145043

jtag newtap auto2 tap -irlen 10 -ircapture 1 -irmask 0x3 -expected-id 0x024090dd

jtag newtap auto3 tap -irlen 10 -ircapture 1 -irmask 0x3 -expected-id 0x020a40dd

jtag newtap auto4 tap -irlen 4 -ircapture 1 -irmask 0x0f -expected-id 0x0958103f

jtag newtap auto5 tap -irlen 8 -ircapture 1 -irmask 0x03 -expected-id 0x00145043

jtag newtap auto6 tap -irlen 10 -ircapture 1 -irmask 0x3 -expected-id 0x024090dd

jtag newtap auto7 tap -irlen 10 -ircapture 1 -irmask 0x3 -expected-id 0x020a40dd

jtag newtap $_CHIPNAME cpu -irlen 4 -ircapture 1 -irmask 0x0f -expected-id $_CPUTAPID

The error messages I got are:

Could anybody help me ?

Many Thanks in advance for your hints

Hi, did you ever find a resolution for this?

We have 10 STM32’s in a chain and having spent the day configuring tools and finally getting things to work I’ve found exactly the same problem…
