Add initial board support for the PocketBeagle 2 from BeagleBoard.org. This is
based on the current official series from Robert Nelson [1] and work from Bryan
Brattlof [2] with some light modifications to protect against certain
configurations changes.
This borrows a lot from Phytec's current DDR fixup logic, as that seems to be
the most complete implementation of a dynamic DDR correction for K3 in tree
currently. Thanks Wadim Egorov and Dominik Haller for setting that up.
I've run coccinelle, checkpatch, and qconfig. That being said, this is my first
contribution to U-Boot so feel free to yell if something looks off. (I may look
into getting qconfig to respect that defconfig include logic in the future, as I
don't like it's suggestions currently. Let me know if it is intended behavior to
flatten that include into a single file.)

This aligns with my understanding of the UEFI spec as well. I dumped the EFI memory map and noticed there were 2 fragmented sections of EFI_CONVENTIONAL_MEMORY that it could still use. Wired up efi_allocate_pages to go to those regions and attempt to allocate from there in the even an LMB_MEM_ALLOC_MAX or LMB_MEM_ALLOC_ANY start failing.

I was able to merge it to the current master and build it, but that of course does not guarantee that it would actually work. I guess that it wouldn't, and I should for now try out your branch as is. But I did not get that far yet. To get a somewhat predictable starting point, I downloaded pocketbeagle2-debian-13.3-base-v6.12-arm64-2026-02-12-8gb.img.xz on a MicroSD card. It booted straight to Debian; I could access it via the USB Ethernet and /dev/ttyACM0 endpoints as noted in https://docs.beagle.cc/boards/pocketbeagle-2/02-quick-start.html. Can you help me enable the USB serial console, first for u-boot and subsequently for the Linux console? Would I have to hold a button while starting it up, or would I need some special u-boot configuration option, or remove one of the files so that the autoboot would fail? Some months ago I used a phyBOARD Lyra (phycore_am62x_*_defconfig), and it was a rather well documented procedure with that one.

Yesterday, a friend gave me an adapter cable that allows me to use an existing 3.3V compatible USB UART adapter. When using the pristine PocketBeagle 2 MicroSD card image, I will get some messages from U-boot, followed by the console output from the Linux kernel and finally from the Debian user space. With any of my self-built images, the SPL is unable to start the 64-bit U-boot: U-Boot SPL 2026.01 (Mar 29 2026 - 15:56:33 +0000) SYSFW ABI: 4.0 (firmware rev 0x000c '12.0.2--v12.00.02 (Clever Cat)') Changed A53 CPU frequency to 1400000000Hz (T grade) in DT SPL initial stack usage: 13416 bytes Trying to boot from MMC2 Authentication passed Authentication passed Authentication passed Authentication passed Authentication passed Starting ATF on ARM64 core... I had a working build script for the phyBOARD Lyra, which I have slightly modified for this experiment. I have a build container that was set up some months ago, as follows: FROM debian:latest RUN apt update&&apt install -y build-essential bc flex bison libssl-dev kmod \ binutils-multiarch gcc-aarch64-linux-gnu gcc-arm-linux-gnueabihf \ python3 python3-setuptools python3-dev python3-cryptography \ python3-pyelftools python3-yaml yamllint python3-jsonschema swig gnutls-dev I set up source directories like this: [ -d u-boot ] || git clone --depth=1 -b master https://source.denx.de/u-boot/u-boot.git \ u-boot [ -d trusted-firmware-a ] || git clone --depth=1 -b master \ https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git/ \ trusted-firmware-a [ -d optee_os ] || git clone --depth=1 -b master https://github.com/OP-TEE/optee_os.git \ optee_os [ -d ti-linux-firmware ] || git clone --depth=1 -b ti-linux-firmware \ https://git.ti.com/git/processor-firmware/ti-linux-firmware.git \ ti-linux-firmware Initially, I used some older checkouts of the other components. Updating them to the latest did not make any difference: the SPL was able to start up also with the older snapshots. Here are the git revisions that I used of the above directories: u-boot: your ef03e35488377a32cdd4f76d1a03ef7f60c798ef trusted-firmware-a: 8dae0862c502e08568a61a1050091fa9357f1240 (Mar 23) optee_os: 1c0c7c06563e9be0ebc55b47cdb71422b02906a6 (Mar 23) ti-linux-firmware: 12.00.00.07 (Mar 20) For podman run, I am bind-mounting the source directory tree using the :O (overlay) option.

Was my assumption about EFI_CONVENTIONAL_MEMORY incorrect? Is this, as > unlikely as I think it is, actually just a known issue right now? Ugh, that took longer than it should have. Alright, what I did would have been correct if there weren't a few issues with other things. Primarily, this memory map for the am6254atl. The U-Boot stack overlaps 2 regions we carve out in device tree. LMB doesn't actually inform the user of this, and just keeps trucking, thinking that the general u-boot reservation will be good enough. Eventually, when some of the stack can be reclaimed, we will put some useful things in these regions that were never properly reserved. What was driving me crazy was that the efiboot selftest reported that everything was okay except for the device tree region. Fun, what could have changed that? Well, that's just efi_carve_out_dt_rsv going back and trying to enforce things LMB never did. Somehow we got it perfectly where copy_fdt would place the device tree squarely in a region that was reserved by the device tree itself. Anything else wouldn't have been exposed to the user. So, I assume that kernel warning is actually a result of some EFI regions being reclaimed by efi_carve_out_dt_rsv and the runtime blowing up because what it thought was a valid address is now in some reserved region. I've checked and am6254atl is also not able to reserve the wkup_r5fss0_core0_memory_region (0x9db00000) at startup due to the u-boot stack size. A ram top value of 0xa0000000 doesn't work with these reservations. Adjusting the CONFIG_STACK_SIZE won't help here, as it u-boot naturally extends into the wkup_r5fss0_core0_memory_region on it's own. I was seeing a stack size of 0x22184c0 locally at the time reservations were being setup. ^ permalink raw reply [flat|nested] 23+ messages in thread

Chicken and the egg issue. We don't know about the memory reservations until after we load a device tree, but we can't load a device tree until we've at least carved out some memory for U-Boot and it's runtime allocations. U-Boot relocates itself to ram_top, which is too close to our reserved regions. I just went in and forced it to relocate to a known region between our reservations and other blob addresses and it worked. Passed all the unit tests and my own runtime tests with efibootmgr. I did also have to adjust add_u_boot_and_runtime and lmb_reserve_uboot_region to handle that arbitrary address and use mon_len instead of just assuming ram_top would be the end. This does bring an interesting question though. If we aren't going to change our r5 and m4 reserved regions then we'll have to make arbitrary gd->relocaddr values more properly supported for both this device and am6254atl. I assume since it's part of the global data it should just be part of the board config instead of a static Kconfig parameter. Anyone from the community got any comments on this? I'm just a lowly graphics developer. ^ permalink raw reply [flat|nested] 23+ messages in thread

This overrides the detection logic with a fixed value. With the ability to detect the board type via the EEPROM, is there any use to having this option? IMO we should just let the board boot with runtime detection for DDR size everytime.

Sadly while developing this, the DT memory values were not passed between the R5 SPL and the A53 SPL ( and thus A53 main ).. After thinking about this routine since I came up with it last month, it might be better to do 2 device-tree's... So with 512MB default path, for 1GB, patch ddr timing in R5/SPL and force 1GB device tree. Then A53/SPL (and main) would have the correct memory size.. Currently, we read the eeprom 3 times, R5 SPL, A53 SPL and A53 main.. (but we only need it really twice, R5 SPL (ddr patch) and the A53 main (device-tree values patching..) > > > + return fdtdec_setup_mem_size_base(); > > + > > + return 0; > > } > > > > +// logic after this block assumes that there is only 1 DRAM bank currently > > +#if CONFIG_NR_DRAM_BANKS != 1 > > +#error Unsupported number of DRAM banks! > > +#endif > > + > > int dram_init_banksize(void) > > { > > - return fdtdec_setup_memory_banksize();

Yeah, I specifically like the option to override the detection logic if users have unusual hardware configs or boards that do not follow the loose identification scheme defined in the automatic fixup path. >> >> > + >> > +choice >> > + prompt "PocketBeagle 2 RAM size" >> > + depends on POCKETBEAGLE2_AM62X_RAM_SIZE_FIX >> > + default POCKETBEAGLE2_AM62X_RAM_SIZE_512MB >> > + >> > +config POCKETBEAGLE2_AM62X_RAM_SIZE_512MB >> > + bool "512MB RAM" >> > + help >> > + Set RAM size fix to 512MB for the PocketBeagle 2. >> > + >> > +config POCKETBEAGLE2_AM62X_RAM_SIZE_1GB >> > + bool "1GB RAM" >> > + help >> > + Set RAM size fix to 1GB for the PocketBeagle 2. >> > + >> > +endchoice >> > diff --git a/board/beagle/pocketbeagle2/Makefile b/board/beagle/pocketbeagle2/Makefile >> > index 3d42c160716..dd529fe6d75 100644 >> > --- a/board/beagle/pocketbeagle2/Makefile >> > +++ b/board/beagle/pocketbeagle2/Makefile >> > @@ -7,3 +7,5 @@ >> > # >> > >> > obj-y += pocketbeagle2.o >> > +obj-${CONFIG_K3_DDRSS} += ../../phytec/common/k3/k3_ddrss_patch.o >> > +obj-${CONFIG_TI_I2C_BOARD_DETECT} += ../../ti/common/board_detect.o >> > diff --git a/board/beagle/pocketbeagle2/pocketbeagle2.c b/board/beagle/pocketbeagle2/pocketbeagle2.c >> > index b6768caa34b..1bfc79350b6 100644 >> > --- a/board/beagle/pocketbeagle2/pocketbeagle2.c >> > +++ b/board/beagle/pocketbeagle2/pocketbeagle2.c >> > @@ -15,15 +15,123 @@ >> > #include <spl.h> >> > #include <asm/arch/k3-ddr.h> >> > >> > +#include "../../ti/common/board_detect.h" >> > +#include "pocketbeagle2_ddr.h" >> > + >> > +DECLARE_GLOBAL_DATA_PTR; >> > + >> > +static int pocketbeagle2_get_ddr_size(void) >> > +{ >> > + // check config overrides first >> > + if (IS_ENABLED(CONFIG_POCKETBEAGLE2_AM62X_RAM_SIZE_FIX)) { >> > + if (IS_ENABLED(CONFIG_POCKETBEAGLE2_AM62X_RAM_SIZE_512MB)) >> > + return EEPROM_RAM_SIZE_512MB; >> > + if (IS_ENABLED(CONFIG_POCKETBEAGLE2_AM62X_RAM_SIZE_1GB)) >> > + return EEPROM_RAM_SIZE_1GB; >> > + } >> > + >> > +#if IS_ENABLED(CONFIG_TI_I2C_BOARD_DETECT) >> > + // dynamically detect the config if we can >> > + if (!do_board_detect_am6()) { >> > + struct ti_am6_eeprom *ep = TI_AM6_EEPROM_DATA; >> > + >> > + if (strlen(ep->name) > 11 && ep->name[0] == 'P') { >> > + /* >> > + * POCKETBEAGL2A00 (am6232 512MB) >> > + * POCKETBEAGL2A10 (am625 512MB) >> > + * POCKETBEAGL2A1I (am625 1GB) >> > + */ >> > + if (!strncmp(&ep->name[11], "2A1I", 4)) >> > + return EEPROM_RAM_SIZE_1GB; >> > + } >> > + } >> > +#endif >> > + >> > + return EEPROM_RAM_SIZE_512MB; >> > +} >> > + >> > int dram_init(void) >> > { >> > - return fdtdec_setup_mem_size_base(); >> > + if (!IS_ENABLED(CONFIG_CPU_V7R)) >> >> I don't have a 1GiB pb2 to test with but I'm assuming the fixed up >> memory nodes get passed from the R5 SPL to A53 SPL and then finally to >> U-Boot as part of fixup_memory_node from k3-ddr.c. > > @Andrei Aldea ^ can you help ;) > Andrei has agreed to give me a board tomorrow so I don't have to test this all through a proxy. >> Could somebody confirm if this is indeed the correct flow?
