I've found that by turning off FIFO the problem disappears. Does anyone know of a FIFO problem with the LPC2212 and eCos? More importantly, anyone know of a fix?

When I did try up eCos PPP between PC and my target (LPC2294) using a serial connection, I couldn't achive the desired results for 115,2K baudrate. But when I turned on the XON/XOFF flow control for eCos serial driver, that became to work just fine. Do you use any flow control on your system? -- Sergei >=20 > Thanks ...Laurie:{) >=20 >=20 --=20 Before posting, please read the FAQ: http://ecos.sourceware.org/fom/ecos and search the list archive: http://ecos.sourceware.org/ml/ecos-discuss -- Before posting, please read the FAQ: http://ecos.sourceware.org/fom/ecos and search the list archive: http://ecos.sourceware.org/ml/ecos-discuss
