Booting fails at low temp, -40C

TI's tech support told me to post this question here =) could anybody help please?

Booting fails at low temp, -40C. At 3PSW, CPSW_SOFT_RESET(0x02D03008 : CPSW Soft Reset Register), when we write 1, it processes reset and becomes 0 when completed. At -40C, at 1(reset) it waits until reset is completed (until 0) and so booting fails. NDK's cpgmacMacOpen seems where it fails.]

(cpsw3g_core.c)

#define CPSW3G_SOFT_RESET_COMPLETE = (0x0u <<0)  #define CPSW3G_SOFT_RESET_BIT =  = (0x1u ><<0)    static void cpgmacMacOpen(Cpsw3gPort *hPort)  {  ......  regs->GMAC[instid].GMAC_SOFT_RESET = CPSW3G_SOFT_RESET_BIT;

while(regs->GMAC[instid].GMAC_SOFT_RESET != CPSW3G_SOFT_RESET_COMPLETE)

{

}
