To muselo dát příšernou práci, a přitom taková blbost...

[pc2005]

Je potřeba otestovat občas nějakej PCI driver a strkat neznámé věci do hlavního kompu se mě nechce.

ukradol si mi nick, ale po slovensky aj tak nevieš

mne napadlo, že toto bude asi Tvoj spam, čiarka, taký nepodarený žartík...

Nepruď a pojď na rande.

Prečo?

Takže... "very"?

Tak koukam, ze jsi moznosti toho MIPSu nakonec dovyzdimal na uplny-uplny maximum, smekam klobouk.

[pc2005]

Jj, ale teoreticky má ten čip ještě dost rezervy. Ale na to už nemám čas překopat půlku kernelu, mám jiné projekty .

máš to moc dlouhý takle ti to nikdy celý nepřečtu :'( příště bys to moh nasekat jako takovej dobrodružnej seriál aby se jako předem nevědělo jak to dopadne :D

[Max]

A proč si to prostě nerozsekáš ty sám?
Co ti brání si to číst několik dní po částech?

protože takhle přečtu jenom začátek pak se toho přežeru a sescrolluju dolu k obrázkům přečtu konec a pak to zavřu a nic z toho nemam :'( ale co je nejhorší je že nás takovejch je strašně moc a bude to ještě horší!

Can You elaborate on JTAG settings?

I need to do some very-low-level debugging (before even u-Boot starts).

Working JTAG would really save me.

Any detail about POD, OpenOCD settings and the like would be *very*welcome.

You can contact me directly at mc5686 at mclink dot it

TiA!

Hi I suppose you have a working JTAG adapter for openocd. other than that it is just a 1-10k resistor connecting TXD1 to the ground (I think, it is like a year back). Rest of the JTAG pins are described on the vocore page.

One config file I've found seems to be this way:

set CHIPNAME mt76
jtag newtap $CHIPNAME cpu -irlen 5 -expected-id 0x1762824f -ircapture 0x1 -irmask 0x1f
set _TARGETNAME $CHIPNAME.cpu
target create $_TARGETNAME mips_m4k -endian little -chain-position $_TARGETNAME
mips32 scan_delay 1000

If you add a definition of your JTAG adapter, the vocore should appear as a standard MIPS device. BTW It is highly possible this configuration I've found in the archives is just an experimental version (one year old...). But I remember it wasn't difficult to detect the chip.

The probing can be done by mem accesses from the openocd or just by connecting the gdb to the openocd server. But I didn't use the JTAG further than that.

BTW check your board if the is not presoldered resistors. The was unassembled spaces on mine very first version from the crowdfunding campaign. You can ask on the vocore forum (this is preffered, there is more people with JTAG problem I assume). The designer of the vocore is helpful .
