[U-Boot] standalone application on odroid xu4
Hi, I'm working with the Odroid XU4 board. I want to execute a standalone application, like the hello_world function that is included with u-boot source. My steps to compile are: 1. clone the u-boot repo 2. `export ARCH=armv7a` 3. `export CROSS_COMPILE=arm-linux-gnueabi-` 4. `make` 5. Use sd_fusing.sh to write the sd card After boot, I use `setenv loads_echo 1,` and then I am able to use the "loads" command to transfer the file "hello_world.srec," but I am notified: CACHE: Misaligned operation at range [0c10, 0c10027a] and when I try to execute the application via `go 0c10 hello world,` it hangs and becomes unresponsive. I've tried the other included srec file, but it also fails in the same way. I've tried defining CONFIG_SYS_DCACHE_OFF and the same with ICACHE, as per a blog post, but that was not effective. I've tried abbreviating the file to include only the app_startup() function and a return, but that also doesn't work. Do you have any advice to help me with this? Ultimately, I would like to write an application that runs automatically before a kernel image is loaded, in order to take advantage of some system hardware that gets locked when the OS boots. Is this possible? Best, Michael Neises ___ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
[U-Boot] Standalone application support in SPL
Hi All, Has anyone come across to the need to run the standalone application in SPL? Due to the onchip SRAM size limitation in our chip, we will need run the small foot print SPL to initialization DDR before we load the u-boot proper to the main DDR memory. We will have to run our DDR initialization in standalone application binary mode due to some restriction of library. I posted a separate thread here https://lists.denx.de/pipermail/u-boot/2019-August/379585.html. Understand SPL does not have a shell to load the application interactively but one can load the binary from flash and jump to its entry point when it is needed during the boot of SPL. I looked through u-boot code and it is fairly straightforward to enable standalone application in SPL. All it takes are adding configure option in spl/Kconfig, makefile changes to include export.c and examples folder and jumptable init in the spl init time. I do need to ifdef the do_reset as dummy for SPL in the _export.h due to the fact that do_reset function is not available in SPL without enabling a lot of supporting code. It looks to me add ifdef is the simplest way to go and does not break any other build. #if !defined(CONFIG_SPL_STANDALONE) EXPORT_FUNC(do_reset, int, do_reset, cmd_tbl_t *, int , int , char * const []) #else EXPORT_FUNC(dummy, void, do_reset, void) #endif Any feedback and comments are appreciated! I can post a patch for review and contribute to u-boot if this sounds a good add-on for SPL. Thanks, William ___ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
[U-Boot] u-boot standalone application license question
Hi, We are looking at the standalone application support in u-boot and we feel it will be a good fit for our DDR initialization code that includes a library that we have no right to distribute in source. But we have some questions in regards to the GPL license exception here: https://gitlab.denx.de/u-boot/u-boot/blob/master/Licenses/Exceptions GPL License Exception: Even though U-Boot in general is covered by the GPL-2.0/GPL-2.0+, this does *not* cover the so-called "standalone" applications that use U-Boot services by means of the jump table provided by U-Boot exactly for this purpose - this is merely considered normal use of U-Boot, and does *not* fall under the heading of "derived work". The header files "include/image.h" and "arch/*/include/asm/u-boot.h" define interfaces to U-Boot. Including these (unmodified) header files in another file is considered normal use of U-Boot, and does *not* fall under the heading of "derived work". -- Wolfgang Denk Looking at the standalone examples/hello_world.c, it now includes common.h(gpl license header) and exports.h(no license header). Same to the stub.c(with compiler.h in addition) which is required to build standalone app. Would that still consider OK and be exempted from GPL license if we follow this example and include both common.h, exports.h and stub.c in our standalone code?

[U-Boot] Standalone Application
I have found very little online about getting a standalone application up and running. I don't have much experience in general let alone firmware level code. What are the steps to creating my own standalone application? I got the hello_world.bin running, but the makefiles are so complex that I don't understand why that is the only standalone app compiled when compiling U-boot as a whole. Do I need to modify one of the makefiles? I have read the readme.standalone, but it doesn't help much for a beginner. Essentially I want to make my own standalone, example.bin, and have it compiled and ran.

If you do not distribute copies of the code, you do not have to release the source code for it. The requirements of the GPL for providing the source code are only for the situation when distri- bute the code. Note however that you would have to be extremely careful - you would have to make very prominet notice in the documentation and the source code that the license exception for Standalone appliations does NOT apply for your modified version of the U-Boot source code. The big problem is that someone could use your extended jump table as base for his own legacy SA applications, while this would be incorrect. May I ask what exactly you are trying to do that triggers these questions? What is the intellectual property in your AS app that appears to be so critical that you cannot release the code under GPL?

[U-Boot] Standalone application on secondary cores
I'm using a SABRE SD board (from Freescale) based on i.MX6 and the u-boot
version is the 2014.04 one. What I've been trying to do is to activate the
secondary cores so that I would be able to use them. First of all I've imported
the commands cpu status/release/reset, then I checked if they were working in
this way:
U-boot cpu 1 status (which gives as result: core1 disabled ...)
U-boot cpu 1 release 0x1200 0
U-boot cpu 1 status (which gives as result: core1 enabled ...)
Next step was to run a standalone application on secondary cores. First I
checked the hello_world application, but it seems that the serial debug for
secondary cores is not set (but I'm not sure). So I wrote an application to
check if I could get changes in memory. This is the simple application (I just
modified the hello_world one):
//standalone app
#include common.h
#include exports.h
volatile int test[5]={1,2,3,4,5};
int hello_world ()
{
int i;
for (i=0; i5; i++) {
test[i] = -test[i];
}
return (0);
}
First I used it on the boot core (core0) with the go command and with the
md command I checked that the results were correct. Then I used the following
command to run it on other cores (the application is at address 0x1200):
U-boot cpu X release 0x1200 0
But when I check with the md command, I can see that there are no changes in
memory.
What should I do to make it work? Am I missing something to set before running
the application on other cores? I'm new to this subject so every suggestion
would be appreciated.
Thank you in advance. ___

Also I have seen that I need to enable #define CONFIG_API but building with this option fails. Current platfom is a AT91RM9200, 16MB sdram, 16MB flash. If I comment out the switches in the net/eth.c net/net.c and include/net.h. It could work. I exported also eth_send. This function doesn't give me any problems when compiling the application.

[U-Boot] Standalone application using saveenv

Are there any intentions to add saveenv function to exports.h in later U-boot releases? I don't want the standalone application to be a GPL program. What I understand when I have read some mailing list threads it is not allowed by myself to add new functions to be exported through the jump table without the standalone application must be a GPL program. What I mean with new functions are functions which already exists in U-boot but not already included in exports.h file, for example saveenv.

[U-Boot] Standalone application compilation
Hi everyone. I'm writing because I have a problem. I'm running u-boot on an
mpc8641 ad I'd like to compile a custom application to make it running on
top of u-boot and I'm unable to compile it. Suppose I want to compile a
simple hello_world application just like this:
int main(int argc, char *arghv[]) {
printf(Hello world!);
return 0;
}
I'd like to write a Makefile to compile and run the application but I always
get a lot of warning and error messages.
So I tried to modify the hello_world application contained into the examples
directory. I don't want to compile it making it together with u-boot. I want
the compilation processes of u-boot and the application to be separated.
Using gcc unfortunately I run into a lot of warnings and error messages.
Someone could help me?

Why don't you help yourself? Configure and compile U-Boot for your
platform, then do a touch examples/standalone/hello_world.c, do a
make again and study what commands are being generated. This is what
you will need to rebuild in your own makefile.
If you do this however, you may notice that it is not very trivial to
separate your application from U-Boot, as you will need the libstubs.a
and the header files. Maybe you would be better off to use what is
available and simply add another target to the makefile in the
standalone directory.

Re: [U-Boot] standalone application for ppc internal registers access
Hi eija_flight, I am using GCC inline assembly in standalone applications to access my cpu (ppc) internal registers.

Re: [U-Boot] Standalone application after powerup
Dear Nagesh.ML, In message [EMAIL PROTECTED] you wrote: What could be the possible solution to include the standalone application in my board powerup sequence? This depends on where you want to include it. I think it is obvious that SA applications require a substantial amount of U-Boot infrastructure to be running. By design, they are intended to be called only when any other interactive command can be exectuted. If you know exactly what you are doing, you may run them a little earlier, but probbaly not much. Me recommendation is: if you want to run SA applications early, you can do this from the preboot hook. Any earlier point may or may not work, and especially there is no guarantee that this will not break in any future versions of U-Boot. Keep in mind what SA applications are used for - especailly, they are NOT intended to sneak in propriatary initialization code in early boot stages, and this is about the only reason I can imagine to use them in that early.
