I have bought two MC13224 USB DONGLE evaluation board for create a network for motion sensors. http://cache.freescale.com/files/rf_if/doc/ref_manual/1322xUSBRM.pdf?fsrch=1&sr=1
As you can see i this data sheet, they explain for erasing the flash i must put two Jumper on pad J3 and J4.
The 1322x USB Dongle has two jumper sites designated as J3 and J4 (see Figure 3-8) located on the
non-component (back) side of the PCB (see Figure 3-5). Use these jumper sites to erase the FLASH.
1. Short Jumper J3 Pin 1 to Pin 2.
2. Short Jumper J4 Pin 1 to Pin 2.
Other datasheet said that i must use the VREFH and VREFL pads too.
Someone can show me where i must weld my jumper for erasing the flash ?
Thanks you very much, by the way if you have other idea for erasing the flash of this device ..
