Kiosk provider seeking an 8051 assembly language developer to patch firmware to: * Add two i2c commands: 1-turn on 2-turn off Notes: 1. Device has pre-existing soft power control. 2. Device has pre-existing operational I2C interface. 3. Current firmware is available only as ROM image. 4. We -possibly- have some C source code for the 8051-based controller, but it is not configured for the product, nor includes past manufacturer provided customizations. It is probably mostly useful as a reference tool. Deliverable Requirements 1. ROM image: a. With new I2C on/off command functionality. b. Upon boot, the device must start in the existing on state. c. All existing functionality must still be operational. d. Provided in the same ROM-able Intel hex format the original firmware image was supplied in. 2. New functionality in deliverable #1 must pass 100 I2C command off/on test cycles. 3. Assembly language listing for deliverable #1, with descriptive comments documenting changes. 4. Deliverables must be provided within 6 business days from when both parties agree to commencement of work. Available Resources We can provide for the duration of the work: * One controller board for development/testing. -and- * One end-product module which uses the controller board. Work Quotation Please e-mail: * Your all-in fixed price for the work. * Relevant qualifications. * The option of partial payment mid-way through project requires two strong references. Otherwise, payment is upon receipt of the required deliverables.
* The ROM image is 128 KB.
* This does require reverse engineering using IDA or similar.
* We have been unable to obtain the datasheet for the microcontroller so presence of a debug interface is unknown.
If interested, please e-mail the information requested in the Work Quotation section to firmware-enhancement-8051 at hcn-inc dot com.
"We have been unable to obtain the datasheet for the microcontroller"
Oh dear!
I'm too busy. I'll have to get my junior onto it.
Zeusti. Hey, Zeusti. Where are you? I've got a job for you mate.

Except that I don't think Zeusti is anyones junior. The quality of his language may vary from lousy to excellent. But the statements are sane.
But I don't think anyone would want to try to reverse-engineer 128 kB of binary in 6 business days, if understating the actual implications of such a task. All risk on the developer with nothing to gain.

If anyone could, I could; and I would do it at least 27% faster than anybody else here because I am so much better than the rest of you. Guaranteed.
But six days for this crazy task is not realistic. I'll let someone else try and watch them fail.
No datasheet, no source code but only ROM IMAGE!! I can hear Warning Alarms already To top it all, Only 6working days to finish the JobFrom worse to Worst
I will not accept the contract even if... 1. God grants me a boon of working 144hrs without blinking an eye. 2. the company is ready to pay me in million dollars
or else i would choose starting date to be one after which i get more of holidays and less of working days....for eg: winter holidays (Christmas). Smart ASS!!! (y leave a million dollar when u can manipulate) :P
@been watching from the sidelines This is no troll. A debate is a healthy debate, if we learn something and a conclusion can be drawn form the it at the end.
remain on the sideline dude!! u already added to troll by leaving ur message, if you didnt-already/dont-till-end learn anything from the discussion.
