How to Reboot G20 after SAM-BA flashing ?

Tue Jul 27, 2010 7:44 pm

Dear AT91 users,

We have a G20 board that right now we are programming by very inelegantly wrapping a simple SAM-BA using .tcl script from a C# windows interface. We use JTAG. The tcl uses send_file calls to program at91bootstrap, u-boot and a kernel to NAND. Then a reboot trigger u-boot to load a root file system (60 MB) over ethernet to RAM, then burns it also to NAND flash, completing the programming.

My question: can I trigger a reboot of the ARM after completing the .tcl script ? The SAM-BA manual shows a Tcl_GO and a go command but naive tries like 'go 0x0' doesnt work. Since this is prior to a re-map I would expected to be able to restart the chip by executing at address 0x0.
