不能,sidecar很多接线口在零售机上是没有的!
除此之外,还需要改几个电阻的。
在Retail to Dev的一份文档中,提到还需要用到叫做Lamprey 板这样一样东西。
Lamprey板,这个不知道是否可以使用自制系统中flash的那个工具实现?似乎他们的目的就是写flash.尽管他有很多功能。像内核调试这样的功能,可以sidecar来实现。
参考6中所提到的,就是合成Flash一个小节。
不知道是否有试过。
国外爱好有人使用Lamprey板成功改过。但是,Lamprey板价格实在太高了,Lamprey board 曾经有人卖过1500欧元。洋垃圾中,好像又没有这个。
参考
To build a Jasper Dev Console PCBA, one should look at the released Jasper DEV PCBA (X819115-001 - PCBA,JASPER,DEV KIT,ICS,HYNIX MEM,512MB FLSH). For debug and testing purposes on a retail PCBA, make the following changes to emulate 99% of a real DEV PCBA:
1) Enable Debug Spew
 Stuff R1C4 with X800601-001 RES,S/M,LF,1.0KOHM,5%,1/16W,0402 (was NO-STUFF)
 Unstuff R1P2 (was X800590-001 RES,S/M,LF,10KOHM,5%,1/16W,0402)
2) Populate Lamprey Headers
 Stuff J2B1 with X804259-001 CONN,HDR,TH,LF,2X7,DUAL-ROW,VERT, PIN 14 KEYED,2.4 TAILS
 Stuff J1D2 with X804260-001 CONN,HDR,TH,LF,2X5,DUAL-ROW,VERT, PIN 10 KEYED,2.4
3) Configure for 256MB Flash if PCBA is not ARCADE SKU (no need flash modification for ARCADE SKU)
 Stuff R2D6 with X800590-001 RES,S/M,LF,10KOHM,5%,1/16W,0402
 Stuff U2E1 with X809112-002 IC,S/M,LF,FLASH MEMORY,256MX8,K9F2G08U0A-P,TSOP-48 or X817006-001 IC,S/M,LF,FLASH MEMORY,256MX8,HY27UF082G2B,(57NM),TSOP-48
 Unstuff R2D5 with X800590-001 RES,S/M,LF,10KOHM,5%,1/16W,0402
 Unstuff R2D7 with X800590-001 RES,S/M,LF,10KOHM,5%,1/16W,0402
 Stuff R2D8 with X800590-001 RES,S/M,LF,10KOHM,5%,1/16W,0402
4) CheckStop LED
 Stuff R8B6 with X800427-001 RES,S/M,LF,2KOHM,1%,1/16W,0402
 Stuff R8A5 with X800601-001 RES,S/M,LF,1.0KOHM,5%,1/16W,0402
 Stuff Q8B6 with X801037-001 BJT,S/M,LF,NPN,SWITCH,2N2222,SOT23
 Stuff D8B4 with X801078-001 LED,LF,GREEN,QTLP601C-AG,0603
5) When building into a console, stuff the following Lamprey cables following standard installation procedures:
 X801796-001 CABLE ASSEMBLY, MOBO, LAMPREY, SMC KERNEL DEBUG PORT
 X801797-001 CABLE ASSEMBLY, MOBO, LAMPREY, SPI PORT
6) Reset the console type from Retail to Dev (Agile doc H03710)
