Greetings,
Oh no :((
I just watched the TS-9420-ARM Production Tool price, it's really too
expensive for me.
Sending back the card will be expensive too (fees, UPS, taxes). My
TS7200 (and addons) costed me 345 euros.
Is there a magic (dirty) way to disable the watchdog ? What about SPI boot ?
I enjoyed my 2.6.11 kernel during one tiny day :(
