Hi Graeme, Thanks a lot for prompt reply and helping me in resolving my problem. The problem was that my board specific code was calling malloc before " mem_malloc_init" being called. Moving my code after calling mem_malloc_init resolved the issue.
Thanks a lot. :-) Thanks and Regards, Sandeep -----Original Message----- From: Graeme Russ [mailto:[email protected]] Sent: 01 June 2012 11:47 To: Sandeep Kumar Cc: [email protected] Subject: Re: [U-Boot] facing issues with malloc in U-Boot Hi Sandeep, On Fri, Jun 1, 2012 at 3:50 PM, Sandeep Kumar <[email protected]> wrote: > Hi , > > I am using vexpress board (ca9x4_ct_vxp).

A few further quick questions: 1) Is this reproducible on multiple boards? Can you rule-out SDRAM component failures? 2) Is mem_malloc_init() being called - I assume so as a) this is a in-tree board without apparent modification and b) malloc() checks for init 3) Is the failure during the first call to malloc()? If not, is the failure always at the same location? I think you are going to need to add some printf() debugging in dlmalloc() Regards, Graeme P.S.
