[PATCH] stm32mp: fix various array bounds checks
by Rasmus Villemoes 19 Apr '23

19 Apr '23

In all these cases, the index on the LHS is immediately afterwards used to access the array appearing in the ARRAY_SIZE() on the RHS - so if that index is equal to the array size, we'll access one-past-the-end of the array.

[PATCH 1/4] configs: am62x_evm_a53_defconfig: Changes in memory map to support SPL splash screen
by Nikhil M Jain 19 Apr '23

19 Apr '23

To enable splash at A53 SPL, need to do memory map changes which involves locate stack above malloc and have enough space to load bmp image above stack. To load a 1920X1200 image a minimum of 8.8MB space is needed, to support it move malloc down to 0x80b80000 from 0x80480000 and bss to 0x80c80000 to have 1MB buffer between malloc and BSS. Observed SPL size 195KB, CONFIG_SPL_SIZE_LIMIT set to 256KB. Observed stack size 1904Bytes, CONFIG_SPL_SIZE_LIMIT_PROVIDE_STACK set to 2KB. CONFIG_SPL_SYS_REPORT_STACK_F_USAGE config sets stack above the malloc and reports for stack overflow.

[PATCH 00/23] arm: dts: k3-am64: Sync with kernel.org and
by Nishanth Menon 19 Apr '23

19 Apr '23

Hi, This is a bit painful series, so apologies in advance for the patchbomb. I did'nt see any clean way to do this, so here goes. First: there are dts mismatches and overrides being done in u-boot in varied manner that should have been submitted to kernel.org in the first place, so, https://lore.kernel.org/linux-devicetree/20230414073328.381336-1-nm@ti.com/ This series picks some of those nodes up and marks them so that merge is a lot more logical. There are still stuff like esm and cpsw that will need a little more work. This series cleans up the dt, switches to .env mode and finally defaults to distroboot with none of the fancy stuff. I have tried to maintain bisectability, but the r5-sk stuff is a bit too broken for me to succeed cleanly.. but it did'nt make sense to confuse review by squashing everything up. Let me know if there is a better bisect option, and I can try.

https://stackoverflow.com/questions/71073386/reading-file-would-overwrite-r… Hi, I had this issue last year and I solved it via device tree. However, I used Yocto hardknott and uboot 2021.04 and Ubuntu 20.04. Now I use Yocto kirkstone and uboot 2022.04 and Ubuntu 22.04 I've been trying to resolve this issue for seven days now. I've already made several changes to the uboot and yocto/device tree configurations without success. Every help is welcome Note I tried: https://dantechrb.com/blog/how-to-build-and-debug-freertos-applications-for… https://whycan.com/t_5474.html
