• JTAG debugging of Ampere Altra CPU

  @Alex Bennée Sorry but I don't know if I can share the document that ADLINK sent me privately, but it's a standard ARM10 header: https://developer.arm.com/documentation/101416/0100/Hardware-...

• JTAG debugging of Ampere Altra CPU

  @Alex Wang Thanks! I had trouble using a ARM-USB-TINY-H but was able to successfully run OpenOCD, connect GDB and get debugging working with an ARM-USB-OCD-HL.

• OpenBMC for ADLINK Ampere Altra systems is now available

  @Will 💜 I haven't come across any compatibility problems, but I have only tried other Macronix chips (64MB and 128MB).

• JTAG debugging of Ampere Altra CPU

  I've been wondering if the COM-HPC-ALT module or carrier exposes any JTAG/SWD/etc. pins? There's what looks to be debug headers on the module, but I haven't had any success connecting my ARM D-STR...

• Access to SMPro telemetry from the BMC

  @Marvin Drees I've asked for access to the MMC code in the past and was told it couldn't be provided. Given that, I wonder if it might be possible to get enough information about the hardware and ...

• Not getting any SOL output from host when running "ipmitool... sol activate"

  Thanks. It's disappointing because I was hoping I'd be able to configure my OpenBMC build to display the consoles but it appears to be something that's just broken.

• [Help Needed] Need the Definition of DB40 connector of A2 board.

  @Willy Tarreau The ADLINK firmware images can be built by end users if they have an NDA signed by Ampere which provides access to the SCP and TF-A binary blobs. The AmpereAltra-ATF-SCP repository i...

• Not getting any SOL output from host when running "ipmitool... sol activate"

  I was wondering if anyone's had any success using the BMC's SOL feature? If I run `ipmitool -I lanplus -U admin -P admin -H <ip_address> sol activate` I don't get any output when I power on ...

• NVME maximum capacity for Ampere platform

  What form factor are you thinking of? I have a 6.4TB NVMe PCIe AIC that I'm successfully using.

• [Help Needed] Need the Definition of DB40 connector of A2 board.

  @Willy Tarreau I have an idea about your slow boot issue. There's basically a race condition between the BMC and UEFI: UEFI wants to use SSIF to read information about the BMC, but it requires that...

• [Help Needed] Need the Definition of DB40 connector of A2 board.

  @Willy Tarreau It would be nice if there was an official build with more verbose logging enabled (DEBUG_INFO at least).

  @Willy Tarreau If you go down the page far enough, there's a release from July 2022, v2.06.100.00: "Update CRB code to V2.06.100-ampere."

• Synchronous Exception at 0x00000000F8222CF4

  @Willy Tarreau Very helpfully, the EEPROMs on the carrier board are all socketed so you can either use an adapter to flash them in-place, or remove them and flash them outside the case.

• Synchronous Exception at 0x00000000F8222CF4

  @Willy Tarreau @Jiaheng Wang was able to create an adapter to connect from a SPI programmer to the DB40 connector on the module, which might be useful?

• CPU frequency capped to 2.3 GHz instead of 2.6 GHz

  @Willy Tarreau Yeah, it's very unfortunate. I didn't think 2.09.100 was released yet. I've been running 2.04.100.10 and 2.04.100.11. Maybe a build of 2.09.100 was mistakenly created?

• EDK2 Github repo disappeared

  @Ruler of COM The 13MB version can also be burned via an eeprom programmer by specifying the offset to flash it at. e.g.   dpcmd --spi-clk 0 -v -a 0x400000 -u edk2_fw.bin
