+Jason <> says:
+ Sort of. The openocd config for the sheevaplug/guruplug is what I use,
+ and is distributed on the dreamplug download page [1]. It does _not_
+ have support for the SPI flash. You can also use the sheevaplug.cfg
+ shipped with openocd. So, I use openocd or tftp to transfer to RAM,
+ then use u-boot to write to flash.
+ To test images, or to reflash, I load the known-good u-boot into RAM via
+ openocd, then I'll either reflash it or load a new testing one from
+ there.
+ To write a u-boot.kwb test image to flash, here is what I do:
+ openocd$ sheevaplug_init
+ openocd$ load_image u-boot # known good from Marvell
+ openocd$ load_image u-boot.kwb 0x00800000 # monster I created
+ openocd$ resume 0x00600000 # run the known good
+ then, in u-boot
+ u-boot$ sf probe 0
+ u-boot$ sf erase 0x0 0x100000
+ u-boot$ sf write 0x00800000 0x0 0x100000
+ If time allows, I'd like to add SPI flash support to OpenOCD.
+ Unfortunately, time is short and the above process works.
