Das Dual SO8W Backup Boot Flash ist ein geniales Tool von DediProg, das den Anwendungscontroller dazu zwingt, automatisch mit den beiden Backup-SPI-Flashs zu arbeiten, die in die SO8W-Sockel unseres Tools eingesetzt sind, und nicht mehr mit den beiden an Bord gelöteten Main Serial Flashs. Beim Anschluss deaktiviert das BBF-Tool automatisch die beiden Main Serial Flashs, die nicht abgelötet werden müssen.
Das BBF Dual SO8W-Tool ermöglicht die Arbeit an zwei Backup Serial Flash, vorausgesetzt, sie werden vom gleichen SPI-Bus und zwei verschiedenen Chip Selects auf der Anwendungsplatine gesteuert.
The BBF tool can be connected to the application with:
- Our BBF cable (included) to the application 2X5 2.54mm pin header.
- Our 2.54mm to 1.27mm cable adaptor-Dual Header( to be purchased separately) to our SMT 1.27mm Pin Headers (to be purchased separately) soldered in place of the Two Main Serial flash footprint for a better stability.
- Our Dual SO8 Test Clip (to be purchased separately) with one SO8 Test Clip to be connected on the First Serial flash package soldered on board and two individual test clips to be connected on the Chip select and Hold pin of the second serial Flash soldered on board (no need of connectors).
The two memories can be easily changed manually thanks to the two SO8W sockets or even updated by connecting our SF100 programmer that can update both SPI Flash independently. The SF100 programmer is completely transparent for the application and will offer to developer high flexibility for code trials or update. The BBF tool is frequently used to boot failing computers and use the Flash Utility tools to update the corrupted Bios memories.
Please note that the BBF modules only support 3.3V/2.5V IC.
For offline programming demand only, it is recommended to use socket adaptor.
Application Hardware Requirement
- The two Serial Flash Hold Pins must be pulled high through resistors (schematics available under request).
- The two application Serial Flash memories must use the same SPI bus and been driven by two different Chip select.
- Email to support@dediprog.com for on-board reference schematic request.
- Download SF100 application note for further information [ AN0103 and AN0106 ].
