[U-Boot] SPL binary too large for OMAP4460 OCM
Hi everybody,
I need to add functionality to the SPL code. I tried to implement in a memory-saving way, however, the SPL is about 45 kB after compilation. To get compilation working, I had to set CONFIG_SPL_MAX_SIZE to (45 * 1024). Now, the SPL as well as u-boot won't boot. After the device' (PandaBoard ES - OMAP4460) reset, nothing happens regarding it's output on terminal.
My question: is it theoretically possible to to establish a successfully booting SPL with ~45 kB in size for this device? The device' on-chip-memory is 56kB so it could fit in there. If so, what needs to be configured / tuned to get it working? Are there any other features I could omit from the binary to make it smaller?
Thanks a lot, -b

Do you have a Secure device or GP ?

if it is Pandaboard? No he has not. I have increased up to 40Kb and it works with serial boot and sdcard/emmc boot.

Sorry i missed to read PANDA. So it is anyways GP. and you changed the CONFIG_SPL_TEXT_BASE as well right ?

First off, sorry for double-posting to this list.
No, the PandaBoard is no HS but a GP device.
This is my configuration:
/* Defines for SPL */ #define CONFIG_SPL #define CONFIG_SPL_TEXT_BASE 0x40303000 #define CONFIG_SPL_MAX_SIZE (45 * 1024) #define CONFIG_SPL_STACK LOW_LEVEL_SRAM_STACK
The MLO binary has 46094 Bytes. Actually I should have enough space (from 0x40300000 - 0x4030bfff -> ~49 kB). However, the device does not start. Right now I am reviewing the code to check, whether it is because of the code and not because of the size that makes u-boot does not start.

Can you try by setting CONFIG_SPL_TEXT_BASE 0x40300350 ?

Hi everyone,
I changed CONFIG_SPL_TEXT_BASE from 0x40300300 to 0x40300350 and sufddenly it works. Do you know why this configuration works, even though with this configuration there are 0x50 bytes less? It even works with a MLO with 47519 bytes.
Here the summary of my config:
/* Defines for SPL */ #define CONFIG_SPL #define CONFIG_SPL_TEXT_BASE 0x40300350 #define CONFIG_SPL_MAX_SIZE (46 * 1024) #define CONFIG_SPL_STACK LOW_LEVEL_SRAM_STACK
Thanks again for the support! -b

Just for testing you can try the following diff: The start address where the Image is downloaded is changed and now the max size is ~46KB.
