How to build eMMC flash programmer MPRG7x30.hex and 7x30_msimage.mbn?
How to build eMMC flash programmer MPRGXXXX.hex and msimage.mbn?
1. Please check if the SConscript is provided in "modem_proc/core p/tools/emmcbld/bulid". If not,you cannot build it with this release.
2. set build environment by executing RVCTXX.bat in build/ms folder
3. go to "modem_proc/core/bsp/build"
4. execute "build emmcbld BUILD_ID=xxxxxxxx"
5. The generated image is located in modem_proc/build/ms/bin/EMMCBLD/
6. MPRGXXXX.hex is eMMC programmer used to communicate with QPST to download msimage.mbn into eMMC.
7. msimage.mbn is used to enumerate the device as a USB mass storage device for all the image updates.
Please refer to modem_proc/core/bsp/tools/emmcbld/bulid/SConscript for how emmcbld and msimage are built and generated.
Using command line to creat 7x30_msimage.mbn
The eMMC Software Download Tool can also be used in Command Line mode for factory? automation and creating boot images.
First find the location of your QPST install,normally under C:Program Files(x86)Qualcomm 5 QPSTbin,that contains your emmcswdownload.exe file. You can either map this location to your 6 path or refer to it directly from the cmd window.
The following command line options are supported for emmcswdownload.exe:
-f <filename> : direct output to <filename> instead of selected device
-s <size enum> : mass storage device size = { “1G”,“2G”,“4G”,etc }
-g <size enum> : write protect group size = { “4M”,“8M”,“16M”,etc }
-x <filename> : partition description file
-p <directory> : search path = path1;path2;…. Etc
-L <filename> : list all connected mass storage drives to <filename>
-i <filename> : image file to write to mass storage device
-w <drive> : mass storage drive to write image file to
In this command line:
? –s and –g options are required,even if no sections are marked as read only
? –s size is only used to set the size of the last partition; it does not affect the size of the output image
? –g is the write-protect size for partitions marked as read only; if there are multiple read-only partitions,only the first and last partitions will be aligned on a protect size boundary
? –L only dumps to the output file,not to stdout
emmcswdownload -f tmp7x30_msimage.mbn -x E:emmcpartition_boot.xml -s 1G -g 64M -p E:emmc;
