Arm925t & Spansion S29WS128J

Post by Splinter34 »

Hello, Is there support for these deivices? I have seen there is support for Arm9, but cannot find out much on the spansion memory. I have enclosed the data sheets for both. I have verified the jtag pinout on my device (an older model radio that I wish to revive). All i really need is to be able to write the entire flash. I already have a good back up. Was ready in my devices service manual that memory writes and reads need wait states and cycles, would this hold true for a blank memory chip? How would this be handled? When I hook up the Jtag It reads one IdCode (03CF1D81) manufacturer not found 6C0. Then Exit thumb mode next line error. I have verified all the pins on my ulink are good by jumpering like the youtube video. Any advice? I have included the data sheets for these devices.

In theory ARM9 is supported. But only limited number of targets are tested. Your target need itself an XML (definition) to be able to read/write.
