Summary

Olimex LPC-2378-STK was the first board I ran NuttX in 2010. Then in 2023 I found this board on eBay and decided to buy it to try NuttX on it again, but for my disappointment it was not working: https://acassis.wordpress.com/2023/04/01/testing-nuttx-again-on-olimex-lpc2378-stk-board/

Then I opened an Issue: #19201 and Xiang Xiao and ldube helped me to get it working again.

Impact

This commit proves that NuttX still working for ARM7TDMI.
