7. After successful updating the QSPI data file is removed from calculator disk
Flashing QSPI using dm_tool (obsolete)
Note that this method is obsolete and will be removed.
The dm_tool takes care about QSPI loader itself. Thus flashing new QSPI contents is as easy as
flashing QSPI and ordinary flash contents in a row:
1. Flash DM42_qspi_xxx.bin
2. Flash DM42_flash_xxx.bin
The second step is important as the ordinary firmware is replaced by QSPI loader in first step.
See Launching dm_tool for details about flashing using dm_tool.
Flashing QSPI using dfu-util
Download QSPI loader firmware DMflash.bin
Get DMflash.bin from the URL http://www.swissmicros.com/tools/DMflash.bin.
Switch the calculator into bootloader mode
From menu or by RESET+PGM buttons (see Bootloader mode activation).
Flash QSPI bootloader
dfu-util -D DMflash.bin -a "@Internal Flash /0x08000000/512*0002Kg" -s 0x8000000
Press RESET button after dfu-util finishes the flashing.
Flash QSPI contents
dfu-util -D DM42_qspi_2.10.12.bin -a "@QSPI Flash /0x90000000/512*04Kg" -s
0x90000000
Press F (top right key) to switch the calculator back to bootloader mode.
Flash main firmware
dfu-util -D DM42_flash_2.10.12.bin -a "@Internal Flash /0x08000000/512*0002Kg" -s
0x8000000
Press RESET button after dfu-util finishes the flashing.
Note that this step is important as the ordinary firmware is replaced by QSPI loader earlier.
