I also tend to think this is a compiler problem. Searching the gcc bugzilla entries for "ldrb" turns up quite a number of hits. I'm not sure which of these we are running into here, but there are enough of them so you can chose freely :-( Best regards, Wolfgang Denk -- DENX Software Engineering GmbH, MD: Wolfgang Denk & Detlev Zundel HRB 165235 Munich, Office: Kirchenstr.5, D-82194 Groebenzell, Germany Phone: (+49)-8142-66989-10 Fax: (+49)-8142-66989-80 Email: w...@denx.de Every revolutionary idea - in science, politics, art, or whatever - evokes three stages of reaction in a hearer: 1.
