u-boot在软重启时挂起

我遇到了这个微妙的问题,如果我将我的ARM设备(U-boot + Linux)置于软重启周期(压力测试)下,它会在100多个周期后失败。我在失败场景中捕获的串行输出是:

 ...
 g_txrx_mode=1
 g_profileid=1
 id=0x1F11 board_type=0x0004 HAS_POE_SUPPORT=1
 Not POE
 read_rbf_header_from_ext4 - filename = e30.core.rbf filesize = 7317252
 cff_from_mmc_ext4:writing e30.core.rbf length 13 num_files 0
 Full Configuration Succeeded.
 crestron_load_rbf: use core e30.core.rbf length 13 rval 1
 Booting from primary
 Writing to MMC(0)... done
 dram_init: id 1f11 (id & 0x0001) 1 has_dsp/has_dante0
 DDRCAL: Success
 INFO  : Skip relocation as SDRAM is non secure memory
 Reserving 2048 Bytes for IRQ stack at: ffe2f708
 DRAM  : 512 MiB

成功重启后,下一行打印的行为:

WARNING: Caches not enabled
MMC:   In:    serial
Out:   serial
Err:   serial

似乎在'skip_relocation()'和'enable_caches()'之间失败了。但为什么经过100多次尝试?这可能是记忆问题吗?内存计时问题?我该如何调试呢?
