SAMA5D3 XPLAINED 开发板测试

wspytu

SAMA5D3提供的IAR例程可通过SAM-BA软件有DEBUG引脚写入开发板中，或通过SAM-BCE ATMEL公司JTAG下载器写入
1.测试电脑使用win7系统，开发板自动装载驱动后如下：

2.使用常用串口调试软件，波特率设置为115200，N 8 1模式，字符形式显示，初始上电“DEBUG串口”输出信息中，
2.1
系统启动信息“AT91Bootstrap 3.6.1-00078-g5415d4e (Tue Feb  4 15:36:46 CET 2014)”
2.2
UBOOT信息“U-Boot 2013.07 (Feb 04 2014 - 15:36:32)”，
2.3
linux内核信息“Linux version 3.10.0-yocto-standard (nferre@tenerife) (gcc version 4.8.1 (GCC) ) #1 Wed Feb 5 10:03:20 CET 2014”(基于3.10.0内核的yocto系统)，
2.4
CPU处理器信息“CPU: ARMv7 Processor [410fc051] revision 1 (ARMv7), cr=50c5387d”
开发板信息“Machine: Atmel SAMA5 (Device Tree), model: SAMA5D3 Xplained”
2.5
“Virtual kernel memory layout:
  vector  : 0xffff0000 - 0xffff1000  (  4 kB)
  fixmap  : 0xfff00000 - 0xfffe0000  ( 896 kB)
  vmalloc : 0xd0800000 - 0xff000000  ( 744 MB)
  lowmem  : 0xc0000000 - 0xd0000000  ( 256 MB)
  modules : 0xbf800000 - 0xc0000000  (  8 MB)
  .text : 0xc0008000 - 0xc05b4fc8  (5812 kB)
  .init : 0xc05b5000 - 0xc05d2d60  ( 120 kB)

  .bss : 0xc063a9f8 - 0xc0663820  ( 164 kB)
”
3.使用ATMEL官网下载的“ATSAMA5D3-XPLD_test_10_public”开发板test_10公版测试文件说明书，将“SDcard_IMAGE”下所有文件复制到SD卡根目录下，连接网线，上电后“DEBUG串口”输出信息
3.1
系统启动信息“AT91Bootstrap 3.6.1-00078-g5415d4e-dirty (Fri Feb  7 11:19:48 CET 2014)”（与开发板初始程序日期不同）
3.2
程序装载由SD卡载入：“
SD/MMC: Image: Read file prod.bin to 0x26f00000
Cmd: 0x1 Response Time-out
SD: Card Capacity: High or Extended
SD: Specification Version 3.0X
SD/MMC: Done to load image”
3.3
板卡信息：“
_[34m----------------------------------------------------------
TEST BOARD APPLICATION

3.4
测试中，网线使用的直连的，没找到交叉网线，所以
网口测试失败“-E- GETH->EMAC <-] .===> FAILED”
编注：网口测试失败：
“[35m-E- FAILED: ReSeT board to test again![0m
-E- Reset board or Wait auto-reboot....” ，
提示重启线路板或等待自动重启再次测试，不会进入3.5- bootstrap开始擦除nand flash存储芯片并写入程序
换上交叉网线后正常：“
_[35m-I- TEST OK : HW BOARD VALIDATED_[0m
-I- BackupReg set and RESET MPU
-I- Wait auto-reboot....
”
3.5
硬件测试完成后，
bootstrap开始擦除nand flash存储芯片“
NAND erase: device 0 whole chip
Erasing at 0x0 --  0% complete.
Erasing at 0x280000 --  1% complete.
….......
Erasing at 0xffe0000 -- 100% complete.

pdf文档中提示：写入程序时间为1分20秒，不要断电插拔USB线
写入程序完成后，开发板“DEBUG串口”输出信息即恢复为初始信息；开发板借用归还时可用SD卡或SAM-BA写入TEST-10恢复为出厂设置即可。
