Why QNX7 does not see all the RAM of the PC?
I use ADLE3800PC with the following parameters:
CPU: Intel Atom E3827 2 ядра, 1,75 GHz, 1MB; memory: 4GB DDR3L.
I run the trial OS QNX7.0 on this PC.
I am using BSP_x86_br-700_be-700_JBN89, the boot file is x86-generic.bin.
I managed to start the OS. Standard applications gles1-gears, gles2-gears, gles3-gears,
sw-vsync are also start. My heavier qt applications do not start.
After looking at the free memory using the pidin info command:
-------------------------------------------------------------------------------------------
# pidin info
CPU:X86 Release:7.0.0 FreeMem:413MB/495MB BootTime:Apr 01 04:32:49 GTM 2019
Actual resident free memory:418Mb
Processes: 29, Threads: 121
Processor1: 197294 Intel 686 F6M1JS9 1749MHz FPU
Processor2: 197294 Intel 686 F6M1JS9 1749MHz FPU
-------------------------------------------------------------------------------------------
I saw that QNX does not see all the PC RAM (496 MB instead of 4 GB).
The same problem with Kontron CP3003-SA, with parameters:
CPU: Core i7 4 ядра, 2,1 GHz, 4MB; memory - 8GB (2x 4GB) SODIMM DDR3 with ECC (instead of 8GB QNX saw only 511MB).
With boot file from BSP_intel-x86_64-APL-abl_br-700_be-700_JBN89, it was not possible to start QNX7 on these platforms,
an Invalid Image OS error occurs.
How to make QNX see the full amount of RAM?
