Update FLASH software from RS-232 - narcispr - Jan 11 10:30:00 2005

Hello! I use a EVM320VC5409 Spectrum Digital board. I would boot this board from FLASM memory. I have seen that is possible write the FLASH program with JTAG emulator an FlashBurn utility. However, I need to change the FLASH software using the RS-232 UART (for comercial use). Is possible do this? Thank you very much!!! Narcís. |

hi, yes, it is posible to do this. but you need to develop the following softwares: 1) an application in the host side which reads and writes to the com port of the PC. 2) functions for reading and writing to the uart registers and buffers. This code wil be running from the dsp. 3) flash writing and reading functions. this will also be executing from the dsp. now suppose you want to send the boottable to the dsp for writing it to the flash. so the host application issues a command to the dsp through uart. the dsp gets ready to receive the data and acknowledges the command. once the host receives this, it starts sending the data which will be recived by the dsp. upon the completion of reception of the entire boottable, the dsp starts writing them to the flash. please note that you need to have a small protocol for the handshaking between the host side application and the dsp application. regards, Dileepan. --- narcispr <> wrote: > > > Hello! > I use a EVM320VC5409 Spectrum Digital board.

We have what we call Live Data Exchange which allows a PC to talk to a DSP target over RS-232. LDX comes with a PC Active-X interface so that you can talk to the controller over Matlab, Visual Basic, Excel, Visual C++ etc. We used this solution for one of our automotive customers.
