[U-Boot-Users] New command loopw
by Martin Krause 11 Jul '04

11 Jul '04

Hello all, here is a patch, which adds a new memory command 'loopw'. In difference to the existing 'loop' command, which implements a read loop, 'loopw' writes to memory in an infinite loop. We use this command to do hardware qualifications on our boards like memory timing measurements with a scope or a logic analysator. To not increase the memory footprint of the default U-Boot configuration, 'loopw' is only compiled in if CONFIG_LOOPW is defined. * Patch by Martin Krause, 29 June 2004: Add new memory command: loopw - infinite write loop on address range Best regards, Martin Krause ------------------------------------------------------------------ Martin Krause TQ-Systems GmbH Gut Delling, Mühlstr. 2, 82229 Seefeld, Germany Email: martin.krause(a)tqs.de http://www.tq-group.com <<patch_u-boot_loopw_command>>
