Hi everybody,
I am using PandaBoard ES (OMAP446) in conjunction with the chipsee
resistive touch screen expansion pack (chipsee.org) for PandaBoard.
The LCD is LVDS signal, it is connect to the CPU with a RGB-LVDS converter.
Is there a possibility to display a splash screen or BMP in u-boot with

Yes indeed, Peter.

When enabling debug mode I get the following error:
dlmalloc.c:2084: malloc_extend_top: Assertion `((unsigned
long)((char*)top + top_size) & (pagesz - 1)) == 0' failed.

Hi,
I need to read a file in spl.c, which is about 675 bytes. I used the
following code:
static unsigned char helperData[675] = {0x00};
s32 err;
uint8_t i = 0;
printf("\n[D] - Reading Helper Data\r\n\n");
err = file_fat_read(filename, helperData, length);
if(err > 0){
printf("[D] - R

This is a proof-of-concept for a technique, which involves
de-/encrypting the u-boot.img with a key derived from a hardware
fingerprint. This is
Hi Albert,
so if I get you right the workflow for payload authentication is the
following:
Encryption process:
1. Create hash value H for u-boot.img
2. Encrypt the hash value H with secret K to get encrypted hash values H_enc
3. Store H_enc
Decryption process:
1. Read H_enc
2. Decrypt H_enc us
Hi everyone,
I want to implement a minimal secure boot architecture into u-boot by
letting the u-boot.img be decrypted during SPL execution. Thus, the
u-boot.img is present on the MMC in an encrypted version. I already
implemented a basic AES-128 en-/decryption algorithm into the SPL.

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'
(Pand
I want to extend the u-boot SPL code with some fuzzy extractor logic by
adding code into
`{u-boot_sources}/arch/arm/cpu/armv7/omap-common/hwinit-common.c`.
U-boot shall be used on a PandaBoard ES (omap4460 SoC).
Thus, first I successfully implemented the code on my x86 pc and I am
porting it to th
