Raspberry Pi 在固件中锁定 Pi 5 内存升级
Jeff Geerling 报道 Raspberry Pi 在固件中加入限制,阻止用户更换 Pi 5 的 RAM 芯片,有时连来自其他 Raspberry Pi 板、容量相同的内存芯片也无法使用。文章引用 rpi-eeprom 仓库 issue 与官方论坛帖作为依据,并解释背景:有人购买廉价的 1GB 或 2GB Pi 5,焊上廉价且有时不可靠的 8GB 内存芯片,再当作全新 8GB Pi 5 出售。作者表示理解 Raspberry Pi 的立场,因为不稳定的内存和不可靠的转售商会带来支持难题。
AI推荐理由 Jeff Geerling 博客引用 Raspberry Pi EEPROM 仓库 issue 与官方论坛帖,说明 Pi 5 固件新增限制,禁止更换 RAM 芯片,甚至同容量其他 Pi 板的内存也不行,并给出背景:有人购买 1/2GB Pi 5 焊上廉价且不稳定的 8GB 内存冒充新 8GB 机型出售。来源为长期跟踪树莓派的知名技术博主,事实指向明确、有链接证据,对硬件与嵌入式开发者有实际参考价值;局限是未提供固件版本号或官方正式公告细节。

Raspberry Pi added a feature in their firmware that restricts users from swapping RAM chips, sometimes even RAM chips of the same capacity from other Raspberry Pi boards. Apparently there were people buying cheap 1 or 2 gig Pi 5s, soldering in some cheap and sometimes unreliable 8 gig RAM chips, and selling them as new 8 gig Pi 5s. Now I totally understand where Raspberry Pi's coming from. They don't wanna support Pis being sold like this, because flaky RAM and dodgy resellers are a huge problem. Especially with how profitable can be in the current AI bubble.
