| 15:24.36 | prpplague | asabil: ask your question |
| 15:25.04 | asabil | could you please check some source code ? |
| 15:28.01 | asabil | actually we got a an mcf523x connected to an eeprom |
| 15:28.17 | asabil | we send instructions, but the eeprom never answers back |
| 15:28.27 | asabil | (checked using an oscilloscope) |
| 15:28.29 | prpplague | asabil: is this known good hardware? |
| 15:28.55 | asabil | yep, tried 2 different eeproms |
| 15:29.04 | prpplague | asabil: and? |
| 15:29.27 | prpplague | you tried 2 and what was the result? |
| 15:29.30 | asabil | signals are sent from the spi to the eeprom |
| 15:29.32 | asabil | but the eeprom sends nothing |
| 15:29.39 | asabil | with both eeproms |
| 15:29.39 | prpplague | asabil: ok, thats not what i asked |
| 15:29.55 | asabil | oh sorry |
| 15:30.30 | prpplague | asabil: is the hardware you are using a known good hardware design, i.e. did you make it or did you buy it as a developer board? |
| 15:30.42 | asabil | what's the question ? |
| 15:31.11 | prpplague | asabil: where did the hardware come from? did you make it or did you buy it from a vendor? |
| 15:31.21 | asabil | ah, parts were soldered here |
| 15:31.48 | prpplague | asabil: so your entire development board was purchase whole? |
| 15:32.08 | asabil | yes |
| 15:32.32 | prpplague | asabil: can you give me the URL of the board ? |
| 15:32.58 | asabil | the board was bought, and the eeprom was soldered to the qspi |

| 15:43.31 | prpplague | asabil: uh, you told me you purchased this board, is that not correct? |

| 15:48.45 | prpplague | asabil: that chip supports several SPI modes |
| 15:49.03 | asabil | oO |
| 15:49.06 | prpplague | asabil: you probably don't have the SPI mode set on the processor that matches the mode on the chip |
| 15:49.09 | asabil | which ones ? |
| 15:49.24 | asabil | oh |
| 15:49.41 | prpplague | asabil: check the section 3-1 in the eeprom datasheet |
| 15:49.43 | asabil | can I ask how can it be set ? |
| 15:49.45 | asabil | is it SW or HW ? |
| 15:50.08 | prpplague | asabil: in software |
| 15:50.17 | prpplague | asabil: you will need to check you datasheet on the processor |
| 15:50.20 | asabil | ok thank you |

| 18:26.31 | GPSFan | prpplague: quick question: it looks like the arm kernel patches are no longer being produced. Are all the arm related patches I see in RMK's patch tracking system sent upstream and do they eventually wind up in the stable kernel? |
| 18:27.39 | prpplague | GPSFan: yea, RMK has pushed all the main line stuff into linus's kernel |
| 18:29.23 | GPSFan | prpplague: this is good I think, so for example the 2.6.19-rc1 patch from kernel.org would have "most everything" currently approved from rmk's patch system. |
| 18:31.27 | prpplague | GPSFan: within reason, yes |
| 18:31.56 | GPSFan | prpplague: yeah I'm sure there is stuff yet to merge, but that |

| 19:36.32 | jbevren | its a sunplus IC, the only one they dont have docs on their site for :) |

| 19:37.23 | prpplague | jbevren: wonder if you can use the cards with the parallax receiver |
| 19:37.34 | jbevren | dunno |
| 19:37.39 | jbevren | I suspect its a rewritable rfid |
| 19:38.38 | jbevren | after running a match, they rescan the card and update the character's stats |
