Hi Jon,

First of all, thanks for your reply.

I want to ask you a few questions:
1. The SDHC 8G memory card is class6? From which brand? (My memory is
Kingston class6)
2. The LSP that came with the EVM is version 1_30_00_23 or
01_20_00_014<https://www-a.ti.com/extranet/cm/product/dvevmsw/dspswext/download/mvl_4_0_1_demo_lsp_setuplinux_01_20_00_014.bin>(this
last updates in June 2008)?

Thabks in advance,

A.Silva
