Any ADSP2191 users here try booting from the UART? I seem to be fulfilling all the requirements but the DSP doesn't start up. Here are the steps I'm following: <UART boot (ez-lite jumpers set to off-on-off)> 1. setup binary loader file in VDSP 2. send "0xaa" for the DSP's autobaud routine 3. wait for a "K" to be returned from the dsp 4. upon the pc's reception of the "K" begin transmission of the binary file My c based windows (polling tx) serial program completes steps 2-4. I get "K" back and complete transmission of a binary file which is 17293 bytes long but the DSP doesn't seem to be running my program. The program I'm transfering was tested previously using the EZ-Lite board USB port. Regards, Tim Dahlin |

You are right that the ldr file must be in binary. I use Tera Term for this purpose. You can download a copy from our website. The second possibility is the Visual DSP version. Version 2 must have SP1 installed!!!! The loader does not work otherwise (at least with SPI which is almost identical). Version 3 also has a loader problem. You can get the correction from ADI.
