So we can sniff that and just try to find out what the last transaction is that happens there.

所以我们可以嗅探它并尝试找出那里发生的最后一笔交易是什么。

My last transaction was on 1st May, and I have checked all the places I have visited since then, but to no avail.

我最后一次交易是在5月1日, 我检查了从那时起我去过的所有地方, 但都无济于事。

So we hooked up an FPGA to do that and wrote some code to analyze the eMMC traffic, and we used the last transaction as a trigger.

因此，我们连接了一个 FPGA 来执行此操作，并编写了一些代码来分析 eMMC 流量，我们使用最后一个事务作为触发器。
