RIFF JTAG – QUALCOMM QSC60XX Generic NOR DLL-s

Posted on by

Resurrector QSC60XX L24 D08 contains only DCC Loader, thus it is to be used only for operations on DCC Read/Write page in the JTAG Manager.
Embedded DCC Loader is designed to work inside of MCU’s internal RAM memory, thus it is not sensitive to external SDRAM configuration or availability or its physical state.

Initial H/W init sequence will setup MCU’s PLL with these parameters:

  • L/M/N = 0x2A/0x00/0x01;
  • Global Clock Divisor = DIV8

You can use these two DLL-s with all QSC6xxx CPU devices with NOR flash.
(Any CDMA phones with Qualcomm QSC60xx CPU, with NOR flash chip)

 

RIFF JTAG – QUALCOM NAND ESM7XXX Generic DLL released

04.03.2011  QUALCOM NAND ESM7XXX Generic DLL released

Resurrector ESM7XXX L41 D04 contains only DCC Loader, thus it is to be used only for operations on DCC Read/Write page in the JTAG Manager.

Embedded DCC Loader is designed to work inside of MCU’s internal RAM memory, thus it is not sensitive to external SDRAM configuration or availability or its physical state.

Initial H/W init sequence will setup MCU’s PLL0 with these parameters:

* L/M/N = 0x41/0x00/0x01;
* Global Clock Divisor = DIV4

If you don’t know what the L, M, N or Global Clock Divisor parameters are, then just keep in mind:

* Highest L values and lowest Global Clock Divisor values will make maximum clocking frequency supplied to the MCU’s core and thus DCC Read/Write speed will be maximum fast;

* Too high frequency supplied to the MCU’s core may result in core overheating or instable operation;
