Maximizing Performance: The Essential Guide to iProg+ Rework

Component Quality: Replacing low-grade capacitors or resistors that cause data corruption. iprog rework

• Buffer Optimization: We increased the SRAM buffer size. Previously, the iProg programmed in 256-byte chunks, leading to massive USB overhead. We bumped this to 4KB, effectively doubling our throughput.
• Error Handling: The old code assumed the best-case scenario. The new code assumes the worst. We added CRC checks after every sector erase and a full verification pass at the end of the cycle.

IPROG Clone vs. Original – Can You Rework a Clone?

Short answer: Yes, but with caveats.

• Phase A: Deploy new iprog alongside old with compatibility adapters.
• Phase B: Switch traffic based on health/metrics; rollback plan ready.

11. Troubleshooting

| Symptom | Likely cause | Fix | |---------|--------------|-----| | No response in Flash Loader | Wrong BOOT0, bad UART connection | Check wiring, baud rate, reset MCU | | Flash verified but device dead | Wrong firmware (different MCU) | Erase and flash correct version | | IProg detected but no functions | Corrupted application vector | Reflash with start address offset | | Random disconnects | USB power insufficient | Use powered USB hub | Buffer Optimization: We increased the SRAM buffer size
