20.07.2012  RIFF JTAG Manager v1.44, RIFF Box Firmware v1.33 Released – Qualcomm Snapdragon S4 support

JTAG Manager 1.44
—————————

  • Added support for a set of QUALCOMM Snapdragon S4 MCUs (like MSM8960): these devices are added to Targets list
  • Added “Override Embedded I/O Voltage” feature: in some rare cases users can use this option to stabilize the weak signals by increasing/decresing JTAG I/O voltage levels, thus overriding embedded voltage settings in a DLL. For this: click “Advanced Settings” button on the “Box Service” page and select a desired voltage level. NOTE, “Override Settings” is valid for current session only, and it is automatically disabled upon next JTAG Manager startup.
  • Few minor rearrangments & fixes.

Firmware 1.33
—————————

  • Added few more processor controll “HAS” script instructions.
  • Added support for a set of QUALCOMM Snapdragon S4 MCUs (like MSM8960).

RIFF JTAG – Samsung Nexus S (i9023) Unbrick Boot repair supported

04.05.2011  Samsung Nexus S (i9023) Unbrick Boot repair supported

Samsung I9023 is based on the S5PCxxx Processor (ARM core is Cortex-A8).
Note, one simple way to connect over JTAG – connect USB cable to PC and insert battery. In this case phone is automatically powered on. But note, in very rare cases it is possible that you will have to hold Power On key during initial connection.
Current resurrector has two different versions of primary boot loaders (PBL) embedded. This depends on hardware version of your phone which boot to use, thus in case of failure (cannot enter download mode after resurrection) of first loader try selecting another.
In case after resurrection (after you have tried with both boot versions) the download mode is not initiated (LCD remains blank) do repeat resurrection with ‘Clone Gremlin zone’ option checked.

To resurrect Samsung I9023:

  • Solder JTAG cable to Samsung I9023 JTAG pads;
  • Connect microUSB cable to phone and PC;
  • Insert battery;
  • Make sure Samsung I9023 is selected in the list of models;
  • Make sure a fixed TCK frequency is selected;
  • Click Resurrect button;
  • Wait till software signals a successful operation completion;
  • Disconnect USB cable, de-solder JTAG wires;

Now phone is in bootable condition, that is, even if it does not start up normally, you can flash it using original Samsung downloader software to restore it to the working state.

To enter download mode:

  • Disconnect PC cable;
  • Insert battery;
  • Hold both ‘Volume Down’ and ‘Home’ keys and press Power-On.

RIFF JTAG – CDMA QUALCOMM QSC1100 Generic DLL released

Posted on by

06.04.2011    CDMA QUALCOMM QSC1100 Generic DLL released

Resurrector QSC1100 X14 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:

  • Clock Multiplier = 0x14

Since few different versions of QSC1100 resurrector may exist (with different multiplier values) you may select the one which suits best to your device.

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

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

Posted on by

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;

RIFF JTAG – Atmel AT91SAM9263-EK NAND Interface supported

Posted on by

16.02.2011   Atmel AT91SAM9263-EK NAND Interface supported

Resurrector AT91SAM9263-EK 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 ATMEL AT91SAM9263 MCU’s internal RAM memory.
Loader has full (read/write) access to AT91SAM9263-EK evaluation board’s NAND memory.

Currently only the 8-bit NAND interface is implemented.
