Switch SD boot source (Yocto and Buildroot) 1737094346125 Yocto: 1. Go to the following path and choose which machine you want to switch the boot source: ~/yocto/sources/meta-ma35d1/conf/machine$ 2. Open the conf and modify 0 to 1 or 1 to 0: UBOOT_CONFIG[sdcard] = "ma35d1_sdcard1_defconfig" 3. Rebuild TF-A and U-Boot: ~/youcto/build$ bitbake u-boot-ma35d1 tf-a-ma35d1 –C compile 4. Clean the current Image: ~/youcto/build$ bitbake nvt-image-qt5 –c cleanall 5. Repack the Image: ~/youcto/build$ bitbake nvt-image-qt5 6. Program the Image to target board Buildroot: 1. Execute Buildroot menuconfig: ~/Buildroot_MA35D1$ make menuconfig 2. Modify Board defconfig and modify 0 to 1, 1 to 0, nand, spinand: Bootloaders ---> (ma35d1_sdcard1) Board defconfig 3. Rebuild TF-A and U-Boot: ~/Buildroot_MA35D1$ make arm-trusted-firmware-rebuild uboot-rebuild 4. Repack the Image: ~/Buildroot_MA35D1$ make 5. Program the Image to target board
Häufig gestellte Fragen / MA35D1 RAM size in Linux is different from hardware
https://www.nuvoton.com.cn/support/technical-support/faq/86b006c2-d716-11ef-bacd-000d3a082cb4/
MA35D1 RAM size in Linux is different from hardware 1737367722063 RAM Size in Linux is Different from Hardware, because VC8000 decoder and display driver reserve some memory You can check it from U-Boot and Linux device tree For example, you can see the Linux kernel device tree below Display driver reserve 48 MB and VC8K reserve 24 MB, so Linux cannot see all the memory space in system Moreover, OP-TEE also reserve some memory ma35d1.dtsi reserved-memory { #address-cells = <2>; #size-cells = <2>; ranges; display_buf: display_buf@0 { reg = <0x0 0x8C800000 0x0 0x3000000>; /* 48MiB */ no-map; }; vc8k_buf: vc8k_buf@0 { reg = <0x0 0x8B000000 0x0 0x1800000>; /* 24MiB */ no-map; }; rproc_buf: rproc_buf@0 { reg = <0x0 0x80020000 0x0 0x60000>; /* 384KB */ no-map; }; };

https://www.nuvoton.com.cn/support/technical-support/faq/e5213b1f-d715-11ef-bacd-000d3a082cb4/
Add an open source library to image 1737367451015 Yocto and Buildroot provide many open source package and library for quickly compile. You don’t need to compile those package alone. Buildroot 1. Enter Buildroot menuconfig: $ make menuconfig 2. If you don’t know where the package is, type “ / ” to search. 3. Compile, re-pack the Image, and program it: $ make Yocto 1. Search the package you want to build: $ bitbake –s | grep XXX 2. Add the package name to ~/build/conf/local.conf: IMAGE_INSTALL_append += “ XXX “ 3. Compile, re-pack the Image, and program it: $ bitbake nvt-image-qt5

Boot source, Secure Build and enable secure boot image 1740990652512 First, you need to write the public and private key to OTP Refer to UM_EN_MA35D1_NuWriter for writing key to OTP Buildroot: 1. Enable MA35D1 Secure Boot and enter the key you want: $ make menuconfig Bootloaders ---> [*] MA35D1 Secure Boot () AES Key () ECDSA Key 2. Rebuild the Image: $ make 3. The otp_key.json will be generated in the folder below: /buildroot/output/images/nuwriter/otp_key.json 4. Write the three keys to MA35D1 OTP by NuWriter: publicx, publicy, aeskey 5. Program the Image to the target board. 6. Remember to switch PG0 ON to enable secure boot. Yocto: 1. Edit the target board configuration: $ vim ~/yocto/source/meta-ma35d1/conf/machine/numaker-som-ma35d1681.conf ... AES_KEY = " " ECDSA_KEY = " " ... 2. Rebuild the Image: $ bitbake nvt-image-qt5 3. The otp_key_sdcard.json will be generated in the folder below: ~/shared/yocto/build/tmp-glibc/deploy/images/numaker-som-ma35d16a81/nuwriter/otp_key_sdcar
